In order to realize multi-function, the radar has wide instantaneous bandwidth and working bandwidth. Unfortunately, the traditional phased array radar antenna by microwave phase shifter or direct digital synthesis in the way of phasing. There are two limitations after increasing the instantaneous bandwidth: "beam squinting" and "aperture traverse delay", which cause the beam divergence and the beam broadening. In this paper, the integrated optical beamforming network technologies are discussed analyzed, which provide certain theoretical support for the research of the future multi-band broadband reconfigurable radar and even the engineering of microwave photonic radar.
