航空集群收发分置协同探测编队构型研究

A Study on Aircraft Swarms Bistatic Radar Collaborative Detection Configuration

隐身飞机雷达波具有前向、侧向散射大,后向散射小的特点,从隐身飞机雷达散射截面的空间差异分布入手,针对航空集群收发分置协同探测编队构型问题,建立集群收发分置协同探测数学模型;基于空间分割法,对影响集群雷达探测能力的两个重要因素,接收机方位角和收-发雷达之间的基线距离进行仿真分析。仿真结果表明:收发分置模式下,集群中任一节点都能形成一定的探测能力;将接收机部署在0°附近,基线距离约为5倍单机迎头探测距离时,收发分置协同探测面积取得最大化,达到雷达单独作用下的5.5倍,此时最远探测边界距收-发基线的距离和探测区最大宽度都取得较大值。

Radar wave of stealth aircraft has the characteristics of large forward and lateral scattering, and small backscatter. From the perspective of the spatial distribution of the stealth target radar cross section, aiming at the problem of aircraft swarms bistatic radar collaborative detection configuration, the model of bistatic radar collaborative detection on aviation aircraft swarms is estab-lished based on space partition method. The simulation analysis is carried out on the direct and important two factors affecting the ability of the aircraft swarms radar detection： the azimuth angle and transmitter-receiver baseline distance. The simulation results show that under the bistatic radar mode, any node in the aircraft swarms can form a certain amount of detection capability, if the deployment of the receiver position is near 0°, and the baseline distance is about 5 times as much as standalone head-on detection range, the maximum detection of collaborative detection area will be obtained, reaching 5.5 times of the action of single detection area. At this time, the distance between furthest detecting boundary distance and transmitter-receiver baseline, as well as maxi-mum width of detection area can have greater value.
