The Decision Method of Electromagnetic Compatibility between Radars Based on the Theory of Signal Detection

Abstract

In order to determine the electromagnetic compatibility between radars better, this paper deduced the distribution character of signal+ noise+ jamming and the signal passing narrowband linear filtering system based on the signal detection theory, and established the quantitative relationship of the radar detection probability and jamming noise ratio on this basis, the detection probability was used to judge the electromagnetic compatibility between radars directly. The simulation experimental results showed that the detection probability was reduced with the increase of interference intensity, when the interference power exceeded the threshold of 1.7 dB, radar detection probability dropped to 50%.
