摘要: 通過分析相位中心偏置天線(DPCA)技術(shù)和干涉處理的優(yōu)點(diǎn)和缺點(diǎn)，該文提出了一種用三孔徑合成孔徑雷達(dá)(SAR)對(duì)地面運(yùn)動(dòng)目標(biāo)進(jìn)行檢測的新方法。該方法不僅能夠檢測出動(dòng)目標(biāo)，還能夠精確估計(jì)動(dòng)目標(biāo)參數(shù)，即確定出動(dòng)目標(biāo)的真實(shí)位置和運(yùn)動(dòng)速度，然后對(duì)動(dòng)目標(biāo)聚焦成像。該文方法簡單，運(yùn)算量小，通過計(jì)算機(jī)仿真數(shù)據(jù)驗(yàn)證了該文算法的正確性和有效性。

Abstract: This paper puts forward a new method of detecting three-aperture Synthetic Aperture Radar (SAR) ground moving targets after studying Displaced Phase Center Antenna (DPCA) and interferometric processing technique. This method can not only discover moving targets but also estimate the targets parameters such as real positions and velocities. Furthermore it is simpler and needs fewer computations. Finally some typical computer simulation results are presented which illustrate the methods validity. -
