A method and system for radar signal processing are included. The method includes transmitting, by a transmit antenna element, a radar signal at a transmit time interval corresponding to a time division multiplexing (TDM) delay; receiving a reflected signal of the radar signal by a receiving antenna element; determining directions of arrival (DOA) respectively corresponding to the transmitting antenna elements by classifying the radar data corresponding to the reflected signal, in which the step of classifying is based on the transmission time interval; determining an explicit element of the phase error elements by applying a radar data-based ambiguous Doppler velocity to the phase error elements of the respective DOA data; and determining integrated DOA data corresponding to the transmit antenna element by integrating the respective DOA data via an ambiguity element that suppresses the phase error element.
包括一种用于雷达信号处理的方法和系统。所述方法包括:通过发射天线元件来以与时分复用(TDM)延迟对应的发射时间间隔发射雷达信号;通过接收天线元件来接收雷达信号的反射信号;通过对与反射信号对应的雷达数据进行分类来确定分别与发射天线元件对应的到达方向(DOA),其中,分类的步骤基于发射时间间隔;通过将基于雷达数据的模糊多普勒速度应用于所述各个DOA数据的相位误差元素来确定相位误差元素的明确元素;以及通过经由抑制相位误差元素的模糊元素对所述各个DOA数据进行整合来确定与发射天线元件对应的整合的DOA数据。
