【 摘 要 】

Based on polarization conversion metamaterial, a novel method to counter single-polarization radar is proposed and discussed in this paper. Due to the resonance feature in the polarization conversion, energy attenuation and waveform distortion dual functions can be achieved. For radar, that will strongly reduce the SNR (Signal-to-Noise Ratio) of the matched filter and the probability of detection. A broadband polarization conversion metamaterial structure was designed with multi resonance frequencies. To evaluate the effectiveness, a typical pulse compression radar model was established, the waveform property, correlation loss in the matched filter and probability of radar detection were simulated and calculated. It was found that the metamaterial achieved the function of passive signal modulation, the echo energy was reduced markedly and great distortion was generated near the resonance frequencies, also the correlation loss in the matched filter was significantly increased especially near the resonance frequencies. Finally the calculated probability of radar detection gave furthermore proof of the effectiveness of the method.
