  • 摘要: 矩陣CFAR檢測(cè)器是根據(jù)信息幾何理論提出的，但其恒虛警特性沒(méi)有從理論上得到分析，且檢測(cè)性能也有待進(jìn)一步提高。該文首先根據(jù)矩陣流形上正態(tài)律的概念從理論上推導(dǎo)了矩陣CFAR檢測(cè)器的恒虛警特性，并在此基礎(chǔ)上，利用積累性能更好的KLD(Kullback-Leibler Divergence)代替測(cè)地線距離，提出了一種改進(jìn)的矩陣CFAR檢測(cè)器。最后通過(guò)仿真實(shí)驗(yàn)驗(yàn)證了改進(jìn)方法具有更好的檢測(cè)性能。
    Abstract: The matrix CFAR detector is proposed according to information geometry theory, but its constant false alarm property is not analysed, and the matrix CFARs detection performance still needs to be improved. Firstly, the matrix CFARs constant false alarm property is analysed according to the normal law on matrix manifold, on this basis an improved matrix CFAR detector is proposed with replacing the geodesic distance with KULLBACK-LEIBLER Divergence (KLD). Finally, simulation experiments verify that the improved method has better detection performance.
