摘要
本文提出了机载相控阵雷达空时二维自适应处理的统一理论，并建立了空时二维处理器系统设计的统一数学模型。根据信号处理域的不同类型，本文把处理器系统分为四大类。本文对这四大类局域处理系统进行了深入研究与分析，给出与提出了多种可能的降维变换。同时提出了局域杂波自由度的概念，为简化处理器的设计提供了理论依据。结合计算机模拟就几种典型的局域处理器进行了性能考察与比较。
In this paper,the unified theory on space-time adaptive signal processing for airborne radar has been proposed ,and a unified model for reduced dimension space-time adaptive processing has been developed. Based on this model,several typical local domain adaptive processors have been studied. Afterwords,a new concept,local domain clutter degrees of freedom , has been presented. It is very useful for designing the processor.Simulation results also have been given and made comparision in this paper.
