Phased Array BeamForming Based on TR Community Microwave Photonic True Time Delay Network
Due to the restriction of aperture effect and the beam deviation, it is the common problem for phased array radar to get wide instantaneous bandwidth under wide scan scope. In this paper, a phased array beam forming system based on the microwave photonic technology was proposed, which can keep high consistency between the beampointing of receiving and transmitting modes and reduce the number of devices. The 16 channels TR community beam scanning system was built and tested. The experimental results show the system can realize beaming scanning under the wide scope of ±30° without beam deviation at Xband, and the beampointing of receiving and transmitting is highly consistent. Combined with the timesharing receiving and transmitting characteristic of the radar system, the scanning and detection capability of the phased array radar system can be effectively improved.
