摘要: |
机载双基地雷达对目标进行探测时,不同的收发平台几何配置和相对运动状态会导致接收到的杂波信号存在较大差异,从而影响目标的检测结果,因此需要研究不同双基场景下的杂波特性。本文研究了机载双基地雷达杂波模拟方法,对杂波散射单元相对方位角、俯仰角等参数的计算提出了一种更具普适性的方法,在此基础上重点分析了机载双基地雷达几何配置、收发波束指向等因素对杂波特性的影响。最后通过仿真杂波的距离?多普勒二维分布验证了本文所提杂波模拟方法的有效性。 |

Abstract: |
When the airborne bistatic radar system detects targets, different geometric configurations and relative motion states of the receiving and transmitting platforms can lead to large differences in received clutter signals, which will affect the detection results of targets. Therefore, it is necessary to study the clutter characteristics in different bistatic conditions. This article studies the clutter simulation method for airborne bistatic radar. A more applicable method for calculating parameters, such as the angle of the clutter cell grids, has been proposed. On this basis, the influence of factors such as geometric configuration of airborne bistatic radar and the direction of the transmitting and receiving beams on clutter characteristics is analyzed. Finally, the effectiveness of the clutter simulation method proposed in this paper is verified by simulating the range?Doppler two?dimensional distribution of the clutter. |
