| Abstract(in English) | This paper proposes a novel digital signal processing (DSP) radar transceiver that consists of a multi-bit quadrature Δ-Σ modulator transmitter and a mismatched filter (MMF) receiver. It can achieve high dynamic range with moderate oversampling frequency while relaxing the requirement for digital-to-analog converter (DAC) resolution. The performance of the proposed transceiver has been validated by computer simulations and experiments. The results for linear FM chirp radar show that the proposed transceiver with 3-bit DACs can achieve high dynamic range of more than 75 dB in range pulse response. |
