摘要: 本文分析了目標(biāo)運(yùn)動(dòng)對(duì)跳頻脈沖雷達(dá)相參合成目標(biāo)一維距離像的影響，并在此基礎(chǔ)上提出了一種以最小波形熵為準(zhǔn)則的最優(yōu)運(yùn)動(dòng)參數(shù)估計(jì)方法。仿真結(jié)果表明，該方法測速精度高，抗噪性能好，可在目標(biāo)距離信息未知時(shí)，實(shí)現(xiàn)對(duì)目標(biāo)速度的精確測量。

Abstract: The effect of target motion on a synthetic range profile produced by a hopped-frequency radar is analyzed,and then a method for optimal estimation of motion parameter of targets is presented based on the least waveform entropy rule.Simulation results indicate that the method can accomplish accurate estimation of motion parameter of targets with a good anti-noise performance. -
