| 摘要: |
| 地面战场侦察雷达因能够提高远距离移动目标的检测能力，提高战场透明度而备受关注。本文主要针对地面战场侦察雷达在存在树木遮挡环境下的信号穿透能力进行试验研究，并重点关注了高频段（S/C/X/Ku）电磁波穿透树林的能力。通过采集H/V极化电磁波穿透不同树林、传播位置、树林/叶簇密度的信号进行处理，对由上述条件变化引起的传播损耗进行了对比分析。试验结果表明，穿树信号受频率和树林/叶簇的密度影响较大，设计时应充分考虑。试验数据对未来战场侦察雷达的工程化设计具有一定的参考价值。 |

| Abstract: |
| Ground battlefield reconnaissance radar has attracted much attention because of its ability to improve long?range moving target detection and battlefield transparency. This paper mainly studies the signal penetration ability of ground battlefield reconnaissance radar in the environment of jungle obstacles, and focuses on the penetration ability of high frequency（S/C/X/Ku） electromagnetic waves. By collecting and processing the signals of H/V polarized electromagnetic wave penetrating through different forests, propagation positions and forest/leaf cluster densities, the propagation losses caused by the above conditions are compared and analyzed. The experimental results show that the tree penetration signal is greatly affected by frequency and density of forest/leaf cluster, which should be fully considered in the design. The experimental data have certain reference value for the engineering design of future battlefield reconnaissance radar. |
