基于ISAR成像的组网雷达带宽自适应调度算法

An adaptive scheduling algorithm for networked radar bandwidth based on ISAR imaging

针对组网雷达系统三维融合成像中带宽资源不足的问题,提出了一种基于组网雷达条件下的ISAR成像带宽资源自适应调度算法。该算法在每部雷达对目标进行特征认知的基础上,利用投影和最大准则对目标进行三维信息融合,再根据融合后信息分析目标在每部雷达中的带宽资源实际需求量,建立组网雷达成像任务带宽资源调度模型,最终实现组网雷达发射信号带宽自适应调整,在保证成像效果的前提下消耗较少的资源。仿真结果验证了该算法的有效性。

Aiming at the problem of insufficient bandwidth resources in three-dimensional fusion imaging of netted radar system, this paper presents an adaptive scheduling algorithm for ISAR imaging bandwidth resources based on netted radar. Based on the recognition of each radar’s target’s characteristics, the algorithm fuses the target’s three-dimensional information using projection and maximum criterion, then analyzes the actual demand of the target’s bandwidth resources in each radar according to the fused information, and establishes a bandwidth resource scheduling model for networked radar imaging tasks, and finally realizes the adaptive adjustment of the bandwidth of networked radar’s transmitting signal. On the premise of guaranteeing the imaging effect, the algorithm consumes less resources. The simulation results verify the effectiveness of the algorithm.
