机动目标的航空集群协同探测策略

航空集群协同探测问题,是集群作战研究的重要内容,其中对隐身目标在不同机动,不同极化方式下的集群动态RCS研究是重点和难点问题。在双基地雷达建模和坐标转换的前提下,对隐身目标的两种典型机动——匀加速机动和匀速转弯机动进行建模,在HH、VV两种极化方式下,运用线性插值法对动态RCS进行时序分析。仿真结果表明,两种机动模型下,随着时间变化,动态RCS起伏波动较大,在匀加速运动模型下,HH、VV极化所引起的RCS差异性较大,匀速转弯模型下,不同极化方式带来的影响较小。

Research of Cooperative Detection on Aviation Aircraft Swarms Based on Maneuvering Target

Cooperative detection on aviation aircraft swarms is an important part of the aircraft swarms operations research,for stealth target in different motor,different polarization mode to study the dynamic RCS of the aviation aircraft swarms is difficult and important problems. Under the premise of bistatic radar and coordinate transformation,the model of uniformly accelerated motion and uniform motion of turning,two polarization mode in HH,VV,the dynamic RCS sequence is analyzed by the method of linear interpolation. The simulation results indicate that,under two kinds of maneuvering mode, as the time change, ups and downs in volatile on RCS, under the model of uniformly accelerated motion,HH and VV polarization caused by the RCS difference is bigger,under the model of uniform motion of turning ,different polarization modes caused by the difference is smaller.
