摘要: |
目标的雷达散射截面积是判断雷达系统中能否检测到目标的重要参数指标之一,为研究以GNSS为辐射源的被动雷达系统下飞行目标的RCS散射特性,仿真了不同机型在被动雷达系统中的静态RCS数据,分析了同一视线角下不同机型的RCS共性及辐射源-目标-接收机位置关系对目标RCS的影响。另外根据设定航路的目标飞行姿态计算得出的雷达视线角,结合飞机静态双基地RCS起伏特性数据,计算了空域中不同位置辐射源对应该航路目标的RCS时间序列,为被动雷达系统的辐射源选择提供了一定参考。 |

Abstract: |
Radar cross section (RCS) area of the target is one of the important parameters for judging whether the radar system can detect the target or not. In order to study the RCS characteristics of flight target in passive radar system with GNSS as the radiation source, the static RCS data of different models in passive radar system are simulated. The RCS commonness of different models at the same angle of sight and the effect of emitter-target-receiver position relation on the target RCS are analyzed. In addition, the radar line-of-sight angle is calculated according to the target flight attitude of the given route. Combined with the static bistatic RCS fluctuation characteristic data of aircraft, the RCS time series of different position emitter pairs in airspace are calculated, which provides a reference for the selection of emitter in passive radar system. |
