“…Due to lack of guard intervals in frequency domain, Doppler shifts produced by mobile targets can destroy the orthogonality of OFDM subcarriers at the receiver (i.e., the ICI effect) and reduce the dynamic range of radar due to increased side-lobe levels [16]. To improve OFDM radar performance, various ICI mitigation approaches have been recently proposed [13], [17], [19], [20]. Considering a single-target scenario, a two-step Doppler estimation method is proposed in [17], where transmit sequences with favorable correlation properties are employed to eliminate ICI.…”

“…For traditional processing methods, a processing method based on the discrete Fourier transform (DFT) is proposed in [19][20][21]. The accuracy of range and velocity depends entirely on the number of subcarriers and pulse accumulation time.…”
