Research on precise positioning technology based on laser active reconnaissance

In order to realize detection and precise positioning of small-caliber visual optical system targets, according to the "cat eye effect" of photoelectric system, the research based on laser active reconnaissance precision detection technology was carried out. The effects of parameters such as laser emission power, receiving aperture and detection distance on the detection performance are simulated. The experiment has verified the ability to detect small-caliber targets under certain laser power. The experimental results show that the 10mm aperture visual optical system at 700m can be accurately detected under the condition of laser peak power of 1000W and laser divergence angle of 1.5mrad.
