在高频天波超视距雷达中,采用发射站和接收站双站分置,而发射站和接收站相隔较远,需要对雷达探测区域建立收发站空间同步覆盖的转换模型,使接收站接收波束覆盖区域与发射站发射波束覆盖区域进行同步覆盖。在已知选定的发射波束覆盖区域的情况下,文中通过设计的转换模型计算出接收波束覆盖区域及其接收波束参数,包括波束中心指向、波束宽度、子波束间隔等,从而实现接收波束覆盖区域与发射波束覆盖区域在空间地理位置上同步覆盖,使雷达系统能有效地探测到覆盖区域内的目标。
In HF sky-wave over-the-horizon radar, the transmitting station and the receiving station are bifurcated, and the transmitting station and the receiving station are far away from each other. Therefore, a conversion model of space synchronous coverage of the transmitting / receiving station needs to be established in the radar detecting area so that the receiving station receives The coverage area of the beam is covered synchronously with the coverage area of the transmitting beam of the transmitting station. In the case of the selected coverage area of the transmitted beam, the coverage area of the receiving beam and its receiving beam parameters are calculated through the designed transformation model, including the beam center point, the beam width and the beam spacing, so as to achieve the receiving beam coverage The coverage area of the area and the transmitting beam is covered in a spatial and geographical position synchronously so that the radar system can effectively detect the target in the coverage area.
