After the range processing and static clutter removal steps, the Capon beamformer based on the steering vectors over a fine 1D azimuth grid (i.e., zero-elevation) is applied to generate the 2D rangeazimuth spectrum matrix (i.e., heatmap). In the Capon beamformer, the azimuth-only transceiver pairs (TX-RX) are utilized to estimate the covariance matrix across the received chirps per range bin. The details about the antenna geometries of the radar boards are given in Section 3.3.1.翻译一下

在经过距离处理和静态杂波去除步骤后，利用在细致的1D方位网格上的定向向量（即零仰角）的基于Capon的波束成形器被应用于生成2D范围-方位谱矩阵（即热图）。在Capon波束成形器中，仅使用方位发射机-接收机（TX-RX）对来估计每个范围距离峰值处的接收到的啁啾信号的协方差矩阵。有关雷达板天线几何的详细信息请参见第3.3.1节。
