摘要
提出了基于PRI的雷达信号分选性能评价指标定义,并根据基于PRI分选原理建立了性能指标模型,仿真了射频目标特征变化对基于PRI的雷达信号分选性能的影响。通过仿真分析,可以看出在理想的分选条件下,当随机噪声方差一定时,随着不同类信号的PRI差值增大,正确分选率随之增大,误分选率随之降低。漏分选率与随机噪声的方差有关,且随机噪声方差越大,漏分选率越小。
This paper presents the radar signal sorting performance evaluation index. According to the principleof PRI sorting, a performance index model is established. And the impact of the variation in RF target characteris-tics on radar signal sorting performance is simulated. The results show that in ideal sorting conditions, the correctsorting rate increases while the false sorting rate decreases with rising PRI differences between different types of sig-nals with a definite random noise variance, to which the missing rate is related the greater the random noise vari-ance, the smaller the missing rate is.
