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。
The per formance of low al titude target detection using bias axis tracking method is studied. The result s hows 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 a nd the visual range are two primary factors to the target detection if the rada r ant enna is too low, while the ground clutter is the primary factor if the antenna i s too high.
