基于似然比检验的STAP检测器及其性能分析

Performance analysis of likelihood ratio STAP detector

基于STAP雷达的信号模型,通过对似然比检验量的推导,得到了似然比检验关系,在此基础上构建了STAP检测器,并在高斯噪声输入的假设下,得出了虚警概率和检测概率与检测门限的关系,以及在给定虚警概率条件下的判决门限。仿真结果验证了理论分析的正确性,以及该检测器具有良好的检测性能。

This paper proposes the STAP detector based on likelihood ratio rule, through the signal model and the likelihood ratio test, deduces the statistic characteristic, and the relationship between detection threshold and false- alarm probability and detection probability. The simulation result validates the correctness of the theory analysis, and the well detective performance of the proposed detector.
