The method of multi-channel phased array radar squint SAR system design

Multi-channel phased array radar has the following advantages: detection multiple target, far work distance, anti-interference capability, and sensitive response, etc. The squint SAR (Synthetic Aperture Radar) is an effective means of detection in complex background in all-weather and all-day. Multi-channel phased array radar needs the consistency of amplitude and phase. The design of the system parameter should focus on the problem of spatial variability properties of PRF and resolution design. This paper introduces the composition analysis of multi-channel phased array radar, consistency of amplitude and phase, and the design of radar system parameters. The result of flight experimentation verifies the method of system design.
