考虑到汽车场景的实时性要求，开发了一种信号处理算法，首次将德州仪器 (TI) AWR1642 芯片组的处理能力展示为具有接收器波束成形的 W 频段 (77-81 GHz) MIMO-FMCW（多输入、多输出 - 调频连续波形）成像雷达。对从 TI 芯片获得的原始 ADC 数据进行后处理，距离分辨率为 4.1cm，角度分辨率为 14.2°，与 MATLAB 中的理论和仿真结果预测的结果相似。
Considering the real-time requirements for automotive scenario, a signal processing algorithm is developed using which, processing capability of the Texas Instruments (TI) AWR1642 chipset is presented for the first time as a W-band (77-81 GHz) MIMO-FMCW (multiple-input, multiple-output - frequency modulated continuous waveform) imaging radar with receiver beamforming. Post processing of raw ADC data obtained from the TI chip gives a range resolution of 4.1cm and an angular resolution of 14.2°, which are similar to those predicted by theoretical and simulation results in MATLAB.
