综合解相关处理是抑制船舶导航雷达杂波干扰的有效措施。本文针对综合解相关处理的重要环节——信号组合方式作了深入分析。文中在两路待处理杂波信号之分布律分别服从于Rayleigh模型和Weihull模型的前提下,导出了各种信号组合方式输出信号的虚警概率和目标检测概率,以最小错误概率准则为最佳准则,通过计算机的数值运算,证明了不同加权情况下各种杂波环境的综合解相关处理的最佳信号组合方式,得出了结论。文中给出了求解所得概率密度曲线和概率分布曲线,还给出了信杂比的计算结果。
The comprehensive solution of correlation and correlation is an effective measure to suppress clutter interference of ship navigation radar. In this paper, an important part of the comprehensive solution to the correlation process - signal combination made in-depth analysis. In this paper, the false alarm probability and target detection probability of the output signals of various signal combinations are derived under the premise that Rayleigh model and Weihull model are the two distributions of the clutter signals to be processed, respectively. The minimum error probability criterion is the best Criterion, through the numerical calculation of the computer, the best signal combination method of the comprehensive solution of various clutter environments under different weighting conditions is proved, and the conclusion is drawn. The probability density curve and probability distribution curve are given in the paper, and the calculation results of signal to noise ratio are also given.
