| Abstract: | The random step frequency signal shares the characteristics of the step frequency radar and the wideband noise radar.It not only reduces the instantaneous band-width and data sampling rate,but also has the good characteristics of the low probability of intercept,the electromagnetic compatibility and the radio-frequency immunity.The statistic characteristics of correlation output and ambiguity function like first moment,second moment,and variance were analyzed,and the radio-frequency immunity of the random s... |
