摘　　要：基于球载发射源,地面接收站的双基地雷达构架,研究了接收DBF技术。首先在所给相控阵线阵的基础上,研究了接收DBF的数学原理及系统实现,讨论了接收DBF实现多波束同步脉冲追赶以达到空间同步的问题,导出了接收DBF实现直达波抑制的最优权表达式,理论分析和仿真结果表明接收DBF较好的完成了照射同步和直达波抑制。Receiving DBF technique is analyzed for a bistatic radar which is composed of a transmitter on a tethered aerostat and a receiver on the ground. The mathematic principle and system implement of receiving DBF of the uniform linear array are researched. Pulse chasing and space synchronization problem are analyzed.The best weight of direct-path wave suppression is derived. Theory analyse and simulation result show that receiving DBF is effective.
