Design And Implementation Of Signal Processing System For Low-altitude Target Detection Radar

With the gradual opening up of low-altitude airspace in China,the security problem of low-altitude airspace has become increasingly prominent,radar has gradually occupied the core position of low-altitude security due to its high efficiency and advanced nature.The low-altitude target has the characteristics of low flying height and small scattering area,which brings certain difficulties to radar target detection.Therefore,designing a high-performance,low-cost signal processing system for low-altitude target detection radar has a certain civil and even military application prospects.The paper mainly completed the design and implementation of signal processing system for low-altitude target detection radar.Firstly,this paper analyzes the signal processing theory of linear frequency modulation pulse radar and its advantages in signal-to-noise ratio gain,clutter suppression and resolution.Secondly,completes the signal processing system for low-altitude target detection radar under the theory of linear frequency modulation pulse radar system,and design the scheme for signal processing algorithm and hardware system according to the system indicators and requirements.Then,designs the signal processing hardware system in detail by using modular design idea,and realizes the radar signal processing hardware system.Finally,debugs and verifies the feasibility of the signal processing system.After debugging and verification,the signal processing hardware system works normally and the algorithm scheme is feasible.The design of signal processing system for the low-altitude target detection radar meets the requirements.
