Target detection method for quasi-continuous wave system radar

Space target monitoring generally adopts a sparse array system, and the conventional single-pulse angle measurement method has low angular precision for the thin array and has an angle blur. In this paper, the coherent accumulation of spatial domain and the coherent accumulation of time-frequency domain can be realized, and the fuzzy target detection can be realized. The sub-array station combined with long and short baselines is used to realize high-precision angle measurement under the condition of sub-array, and the effect of de-blurring is achieved. Simulation results show that this method can effectively achieve the target detection of quasi-continuous wave radar.
