摘要

在实际的雷达检测环境中

杂波、热噪声等产生的干扰功率通常是未知的.为此

Gini F提出了一种估计干扰功率的方法

并给出一种自适应序贯假设检验方法检测位于同一距离-方位分辨单元内的多个目标.不过

所提估计方法存在门限很难确定的问题.针对该问题

本文提出了一种新的估计干扰功率的方法

并推导出相关门限的理论值.在新估计方法基础上

给出了一种改进的自适应多目标SHT检测方法.仿真证实

改进后的自适应SHT方法具有更好的检测概率.

Abstract

In a realistic radar detection scenario

the disturbance power generated by thermal noise and clutter is unknown.So Gini F proposes a method of estimating the disturbance power and then presents an adaptive successive hypotheses test (SHT) procedure to detect the multiple targets in the same range-azimuth resolution cell of a radar system.However

it is hard to get the threshold for the estimation method.Aiming at the above problem

a new estimation method is put forth and the value of relative threshold is derived.An improved adaptive SHT procedure based on the new estimation method is given.The simulation results show that the improved adaptive SHT procedure has a better detection probability.
