Evalution on Anti-jamming Efficiency of Coherent Sidelobe Cancellation
It is addressed that the anti- amming efficiency of CS C Coherent Sidelobe Cancellation could not be only evaluated by C Cancellation atio , but also by the detection range change between before and after CS C. According to orthogonal principle, by introducing the correlation coefficient between the main and auxiliary amming signal, it could be simplified to calculate the C of CS C. The mathematical models of C of the single and double CS C are set up considered the receiver noise, and the static simulations are made. The results indicated that the amming signal could be canceled to the noise level by single CS C when the amming signals of main and auxiliary channel are cohered completely, but the amming signals level will be higher than the noise s level when the channels are not cohered completely and ammer-to-noise ratio is high. The CS C has a strong anti- amming performance for cover noise amming.
