摘要: 本文針對機(jī)載側(cè)面相控陣?yán)走_(dá)的雜波譜特點(diǎn),提出了一種基于列子陣結(jié)構(gòu)的先時后空局域聯(lián)合二維信號處理方法。文中對該方法的原理和性能作了較詳細(xì)的討論,并與其它兩種方法作了比較,理論分析和計算機(jī)模擬均表明新方法的性能和容差能力較好,特別是在主雜波附近區(qū)域的改善因子有明顯的提高。Abstract: A new partial joint-domain spatial-temproal adaptive processing with time-space configuration is proposed, based on the properties of clutter returns received by an airbore phased array radar on which a side phased array antenna is placed. The principle and performance of the propsoed processor are analyzed in detail, and compared with those of two other processors. Theoretical analysis and computer simulation results show the excellent performance of the processor, particularly when targets are close to mainlobe clutter.
