Optimal binary detection for distributed targets

研究了高斯白噪声背景下扩展目标二进制检测器的优化问题。散射中心展布特性是制约二进制检测器检测性能的重要因素之一。首先从理论上系统分析了不同的散射中心展布对二进制检测器检测性能的影响,然后采用经验拟合的办法给出了设计最优二进制参数的经验公式,进而得到最优二进制参数设计的一般原则。仿真结果证明,最优二进制参数和距离像的长度及散射中心的个数有关。

The optimizing problem of a binary detector for distributed targets in Gaussian noise is studied.The performance of the binary detector is restricted by the distribution characteristic of scattering centers.Firstly,the relationship between the distribution characteristic of scattering centers and the performance of the binary detector is analyzed in detail.Then,the optimal binary parameters are given in the form of an experimental formula,and the principle of designing optimal binary parameters is proposed.Finally,the results of simulation prove that the optimal parameters are determined by the length of profile and the number of scattering centers.
