机载有源电扫描阵列(AESA)雷达以数百乃至上千个发射/接收模块构成有源天线阵列.通过控制各 T/R(发射/接收)模块发射电磁波波束的相位实现雷达波束方向的改变.这种电子控制的扫描
The Active Antenna Array Scanner (AESA) radar consists of hundreds or even thousands of transmit / receive modules to form an active antenna array. The beam direction is controlled by controlling the phase of each T / R (transmit / receive) module transmitting the electromagnetic beam Change. This electronically controlled scan
