Antenna selection in radar system based on multiple detection objects and multi-step planning

A radar system includes an antenna element and a receive channel. The adaptive switch couples the receive channel to the subset of antenna elements as selected antenna elements. The selected antenna elements receive reflected signals reflected from the object, and each receive channel outputs a digital signal based on the reflected signals from the coupled selected antenna elements. A controller processes the digital signal from each receive channel to estimate a direction to each object and generate a candidate configuration of switches. Evaluating the candidate configurations includes performing a multi-step evaluation using a decision tree rooted at each candidate configuration and checking the accuracy of the output at the last step of the decision tree to select a selected candidate configuration based on the accuracy. The switch is configured according to the selected candidate configuration prior to receiving the reflected signal for the next iteration. 雷达系统包括天线元件和接收信道。自适应开关将接收信道耦合到天线元件子集作为经选择的天线元件。经选择
