Abstract

A long-distance, high-efficiency "cat’s-eye" target laser active detection method based on the characteristics of target echo spectral segments was proposed. Considering the target echo generation condition, multiple sets of different wavebands, high-frequency and short-pulse detection lasers are used to obtain the high-precision distance value of the detection target, and simultaneously record the echo intensity information of the detection signal for different spectral segments. Analyze the relationship between the target distance, the target feature, the probe band and the beam quality, correlate the distance with the spectrum information, calculate and identify whether the target is a "cat’s eye" target. In the experiment, 1064nm and 1550nm laser sources are used to detect and analyze different types of targets. The test results show that the detection method can quickly and effectively obtain the multi-spectral echo reflection characteristics of the target, and achieve the "Cat’s Eye" target detection in the kilometer range. Effectively reducing the number required for target identifies feature points, improves the recognition efficiency and accuracy, and reduces false alarms.
