| 摘 要： | 分析了偏轴跟踪抑制多路径误差时雷达低空检测性能。结果表明 ,在近距 ,雷达检测性能由SCR决定 ;在远距 ,由SNR决定 ;雷达天线过低 ,探测空域受过渡距离和视距限制明显 ;天线过高 ,探测空域受地杂波影响明显。

| Abstract: | The performance of low altitude target detection using bias axis tracking method is studied. The result shows that the detection performance is restricted by SCR for short range target, by SNR for long range target. The result also shows that the transition range and the visual range are two primary factors to the target detection if the radar antenna is too low, while the ground clutter is the primary factor if the antenna is too high. |
