Design And Analyse Of Electrical Laser Ideification System

By the rapid development of science and technology, the figure andintelligence of the armored cars have a great progress in our army,especially in recent years, by the using of Electronic warfare. Electronicconcealment technology, camouflage technology and simulation technology.The system of laser identification of friend or foe has been become theimportant department of military equipment. The traditional radio contact,and the semaphore handing have been abated; the new laser identificationtechnology has been got the development and using.Because of the laser has a high requirement for the emitting andreceival equipment, and the modulation and quality of laser emitting wasdecided by the following quality of the power supply. The high quality laserhas a high requirement for the power supply, at the same time, for thesensitivity speed of response, vignette measure of laser receival installationto set up an amount of loss. The ray radiation instrument of high efficiencysensitive and high multiplying power is the pursuant aim always in the laserreceiving. So the article has a useful probe from the emitting and receivalequipment of laser, refer to the advanced technology, meanwhile use forreference from technology data in the other army. To research the basicfunction of the emitting and receival element seriously. To compare and testthe power expend, frequency responsev, and photoelectric efficacy at lastdecided to use the high speed VMOSFET and IRF450 as the power button.The button controls the active pump of semiconductor laser.It has somecharacteristics of small bulk, high power, high working frequency responsevand the wide changing frequency big wave electric current. It can satisfy theworking requirement of laser for the pump. The reception machine of laserecho wave adopted the APD silicon photocell. This photocell was the LEDwith reach-thorough and avalanche, it has high speed of response,narrowspectrum difficult to be disturbed, sensitive border spectrum dropping rate. It also has some selection,high photoelectric efficacy and stable workingcharacteristics of intense. In the meantime to select the emitting and receivalmeticulously, and to analyze and count the power supply system. At lastdesign the feasible LSC(Laser serro circuit).
