Abstract:

Unlike the existing resonance region radar systems(RRRS)that transmit the orthogonal frequency division multiplexing(OFDM)multi-carrier waveform, the dense multi-carrier(DMC)radar waveform which has a narrower frequency interval than the traditional OFDM waveform is proposed. Therefore, in the same frequency bandwidth, the DMC waveform contains more sub-carriers and provides more frequency diversity. Additionally, to further improve detection performance, a novel optimal weight accumulation target detection(OWATD)method is proposed, where the echo electromagnetic waves at different frequencies are accumulated with the optimal weight coefficients. Then, with the signal-to-noise ratio(SNR)of echo waveform approaching infinity, the asymptotic detection performance is analyzed, and the condition that the OWATD method with the DMC outperforms the matched filter with the OFDM is presented. Simulation results show that the DMC outperforms the OFDM in the target detection performance, and the OWATD method can further improve the detection performance of the traditional methods with both the OFDM and DMC radar waveform.
