doi:10.3969/j.issn.1000-1093.2018.06.008

Abstract

Abstract: A pulsed laser echo model is established for the problem of low rangefinding accuracy of pulsed laser fuze in high speed dynamic test. Based on the laser radar equation, the actual emission waveform and light intensity distribution are used to derive the power equation of echo signal by the analytic method. The influences of different parameters on the echo waveform and signal-to-noise (SNR) are analyzed in considering the surface characteristics and structure size of target. The echo experiment of pulsed laser fuze is made. The results show that the peak value decays and the peak time moves forward as incident tilt angle increases. Key

Key words: pulsedlaserfuze, planartarget, echocharacteristic, heavy-tailedfunction, ellipticGaussdistribution
