8、ary field. Photoelectron technology in military field use has expanded from visible light fields to light ends, infrared and ultraviolet band. All sorts of infrared devices, such as infrared cameras, infrared tracker,

9、 infrared search and tracking system (IRST) have been applied. Compared with infrared mode, ultraviolet band used in military applications is late, its unique advantages is more and more attention by all the military

10、. The warning technology in missiles approaching alarm is full of using ultraviolet missile alarm equipment also received considerable development. Infrared alarm system works in passive way with good own concealment,

11、 strong anti-jamming capability, target detection range. The high precision and operating distance is more than ultraviolet alarm indicator and some other advantages which become the main technology method for milita

12、ry warning. In the late 1980s, infrared focal plane array detector rapid development and gradually get used to provides the technical guarantee for develop advanced infrared alarm system. Facing the increasingly serio

13、us battlefield of missile threat, countries all over the world have developed various Missile Early Warning System (MAWS/Missile Warning System) ensure the safety of combat facilities. How to find the threats early an

14、d make accurate judgment has become an urgent problem for MAWS. The missiles approaching warning technology is a new optoelectronic countermeasure technique which is developed in nearly 20 years. This paper expounds

15、the background of the development of missile warning technology, analyzes the technical principle and main properties of the system to determine the ultraviolet imaging detection of photon receiving, key technolo

16、gy, the technological development of the evolution and the latest development of the field. II. PRINCIPLE OF INFRARED-ULTRAVIOLET WARNING SYSTEM Infrared alarm system is using infrared radiation of target and it’s

17、 reflective to determine the orientation and give timely warning. Any object if temperature above absolute zero can to emit radiation, infrared wavelengths have a proportion so the detector can detect it, but because

18、the problems of the ground fire, buildings, and the sun flashing and horizontal level, the infrared warning false-alarm rate is high. Ultraviolet warning is through detecting ultraviolet of plume smoke and fire platf

19、orm of missiles so as to provide for short-range tactical missile close-in defense. Because ultraviolet detection wavelength is in sun dead zone, space of ultraviolet radiation is less. Easy detection of signal and fa

20、lse-alarm rate is low. Ultraviolet detector has advantage such as simple structure without low temperature cooling, no scanning and small volume, light weight, high detection sensitivity and etc. But the ultraviolet

21、detection signal is weak and the effect distance is short. Therefore, the target photoelectric defense alarm system adopts infrared–ultraviolet double-color detection technology, it increases the detective wavelengths

22、 of target when the detection of infrared-ultraviolet comprehensive alarms can fully exert missile warning system of infrared detection distance and advantage of the warning system of missile false-alarm rate is low.

23、 It greatly increases the effectiveness of alarm. Alarm system mainly includes three parts, as shown in Fig.1, grey square, namely ultraviolet detection unit, signal processing unit, display and control unit. Detecti

24、on unit usually includes several ultraviolet detectors combined to form the angle of all-round and airspace covered. After the detector detects the infrared-ultraviolet radio signal through photoelectric transformatio

25、n, it sends the signal to 2010 International Conference on Test and Measurement 978-1-61284-030-7/10/$26.00 ©2010 IEEE ICTM2010 382Figure 2.The Architecture

26、 of target-tracking and detection circuit board C. PCI interface design PCI interface play a role of bridge in the three DSP （DM642）and IXP425. All data exchange is through PCI in order to improve the signal integrity a

27、nd reliability, this design uses the topological structure of the chrysanthemum-chain, and the simulation to confirm the signal integrity. D. The clock and reset design Any one processor should have at least one clock

28、 source. In the internal processor, there have a corresponding clock management unit to provide appropriate clock for each function control units. For the whole system synchronous, 33MHz active crystal through the bu

29、ffer provide all PCI clock; similarly three DSP clock is needed to process synchronization to ensure the data properly exchange and transmission. It uses MAX706 to accomplish the whole board reset. E. Power design To

30、tal input power is 5V, using LM2596S-ADJ to accomplish the transformation from 5V to 1.3V, using TPS54610 to accomplish the transformation from 5V to 1.4V, using another TPS54610 to accomplish the transformation from

31、 5V to 3.3V; DM642 need precision and stability double- power supply, one for the core voltage 1.4V CVDD, another is 3.3V for peripheral voltage DVDD; the core voltage of IXP425 is 1.3V, the peripheral voltage of IXP

32、425 is 3.3V;it also consider the order of power on to ensure device can steadily work. IV. THE DEVELOPMENT TREND OF WARNING TECHNOLOGY A. The Development to high-precision bearing orientation The existing infrared alar

33、m systems are in the threat warning phase in most time which has a distance from ideal the electro optical countermeasures. In order to eliminate the threat in time, it demand the future alarm system not only have th

34、e ability to accurately determine threatened species, but also locate it to request the alarm system with high resolution and high sensitivity, wide angle cover and high performance intercept probability. B. The Devel

35、opment to composite alarm With the development of infrared technology and laser technology, RF technology, the number and type of threat are increasing rapidly. Work band of the existing infrared detector is generally

36、 1um~3um, 3um~5um and 8um~12um. Therefore, the development using radar and infrared, laser technology integrated compound photoelectric detector, and expanding its response spectrum, it reduce false alarm rate and im

37、prove the ability to identify and multi-objective processing. It can satisfy the need of photoelectric battlefield in the future. Such as the United States air force develop the composite alarm for B2 plane can simul

38、taneously detected infrared, ultraviolet, and visible and RF threat. C. Multi-functional alarm integration Infrared alarm system combines with other warning systems such as radar, laser warning devices. It integrates w

39、ith fire control system to constitute automation and incorporate alarm system. Canada has make a plan to combine the infrared alarm system, the TASMK23 torpedo capture system and AN/SLQ EW support equipment into a ne

40、w Internet electronic monitoring equipment. Due to the TAsMK23 has an ability of detecting of high elevation flying and AN/SLQ2 could provide remote target alarm. D. Adopt more advanced technology In order to improve

41、warning capability, infrared warning system needs to adopt more advanced technology constantly. With the high detection rate, high response rate of focal plane array devices are developed and used, infrared warning s

42、ystem would have a higher detection sensitivity and resolution, higher intercept and lower the probability of false alarm rate. With the development of large scale integrated circuit technology, the system will improv

43、e the signal processing speed constantly. With the development of large scale integrated circuit technology, the system will replace the computer with small, powerful and fast MCU. The whole system develops to the di

44、rection of module and components development so as to reduce the size, weight and improve the stability of overall performance. With the development of data processing technology and infrared array detectors, the inf
