| 摘 要： | 对于非瑞利杂波中的目标检测问题,人们做了大量工作,比较典型的一类是局部最佳以及近来的渐近最佳检测器(AOD),其渐近性能大大优于线性检测器(LD).由于独立脉冲数N不可能太大,所以研究AOD的次极限性能是有必要的.对于韦伯尔杂波背景,本文做了类似文献1,2]的工作,但模拟表明十分困难,通过采取一些必要的修正,本文仍获得了一个比较理想的混合检测方案,对于有限N值该混合检测器(HD)性能优于AOD和LD.

| Abstract: | The asymptotical (large sample size) performance of the coherent asymptotically optimum detector (AOD) for targets embedded in non-Rayleigh clutter is discussed. Computer simulation has been made for the performance of AOD for moderately large sample size. It is shown that, with a moderately large sample size, the expectation value of the asymptotic theory cannot be reached. A simple hybrid detection scheme is proposed for weibull clutter and it is found that it performs better than both the AOD and linear detector. |
