【Abstract】 The operation principle of laser fuzes with six-quadrant detector is analyzed. Taking a helicopter as the target, the rotor-identification criteria of rotorcrafts are set up. Signal pre-processing and the function of the related circuit are analyzed. Under the complicated circumstance, target identification and target distance and azimuth estimation are realized with the help of a DSP. The flow chart of the signal processing program is given. The feasibility of the method is proved by experimental test results.更多还原
