摘要
天空双基地预警雷达空间同步效果评估与优化是其空间同步技术的重要一环。首先,提出了空间同步效果的评估指标,分析其三大影响因素;其次,针对每个波位需要的波束驻留时间不同的问题,提出了脉冲积累优化方案,对其工作流程和相关参数计算进行推导;然后,从对波位编排灵活控制的角度提出了波位编排优化方案;最后,设计仿真实验对两种同步效果优化方案进行验证。仿真结果表明:两种优化方案可以使得接收信噪比和空间覆盖率的空间分布更加均匀,提高了发射能量的利用效率,有助于空间同步效果的优化。
In this paper,we study the evaluation and optimization of spatial synchronization of space-air based bistatic early warning radar.First,this paper proposes the evaluation index of spatial synchronization effect and analyses the three main factors.Secondly,for different dwell time of each wave,the pulse accumulation optimization is proposed,the work flow and the relevant parameters are deduced.Then,the beam position arrangement optimization is proposed for flexible arrangement on the beam position.Finally,the simulation experiments are made to verify two kinds of synchronization optimization schemes.The simulation result shows that the two optimization schemes can make the SNR and spatial coverage of the spatial distribution smoother and improve the utilization efficiency of emission energy which can contribute to optimization of spatial synchronization effect.
