摘要: 本文通過(guò)對(duì)AMTI和SAR信號(hào)處理算法的分析,提出了一個(gè)完整的AMTI與SAR兼容的雷達(dá)體制處理模型,并對(duì)該體制的可行性進(jìn)行了深入的理論論證。計(jì)算機(jī)模擬結(jié)果表明,該系統(tǒng)不僅具有對(duì)靜止目標(biāo)的良好成像能力,而且能成功地檢測(cè)出強(qiáng)地雜波背景下的運(yùn)動(dòng)目標(biāo)。

Abstract: Based on the analysis of Adaptive Moving Target Indication (AMTI), and the signal processing of Synthetic Aperture Radar (SAR), a complete compatible system of AMTI and SAR is put forward. The compatibility and effectiveness of this system is proved in theory. The resutls of simulation show that this system not only has the good ability of imaging stationary targets but also has the ability of detecting moving targets under the background of strong clutter. -
