Abstract

A dual-channel active laser detection system based on an Avalanche Photo Diode(APD) and a Charge-couple Device(CCD) is designed to effectively detect weak echo signals of "cat-eye" targets and to acquire the intuitive image information of a target area. Firstly

the concept of hardware design is introduced

including the functions and constitution of some modulies and the types of primary assemblies. Then

based on the key problems of designing receiving-magnifying circuit in the APD detection mode

the circuit constitution

working principle and the selection of main parts are discussed

and the match of response spectrum for the CCD and laser is analyzed. Finally

the detection experiments are performed by using typical "cat-eye" targets at different distances. The experimental results show that the echo signal power of the typical "cat-eye" target is 2.87 times that of mirror-like surface at a distance of 550 m in the APD mode; and the echo signal power of a telescope and that of optical window for a laser finder are 2.72 times and 2.31 times those of background at distances of 550 m and 2 500 m in the CCD mode

respectively. The dual-channel active laser detection system can capture the "cat-eye" targets from background and jamming targets easily

which proves the rationality and validity of the proposed system.
