An Evaluation Method of Anti-jamming Performance to Receiver Based on Sample Entropy
Aiming to make a quick and right evaluation of the anti-jamming performance to receiver, an evaluation method is put forward, in which the sample entropy (SampEn) values of input and output sequences of receiver are evaluation indexes. The analysis of simulation signals SampEn validates the rationality of SampEn substituting for Signal to Noise Ratio (SNR), because SampEn does not change with the change of signals amplitude, and monotonically decreases as SNR increases when SNR is in certain range. The evaluation method is able to solve the problem that the SNR gain is difficult to compute, because of the uncertain relation of signal and noise and the distortion in the receiver process. The method can also avoid the huge statistical computing, which achieves the purpose that the receivers anti-jamming performance is evaluated only by input and output sequences, without any other conditions. Lastly, an experiment validates the feasibility and effectivity of the proposed evaluation method.
