Digital Compensation Technique for Wideband Phased Array Radar Using Nonlinear Frequency Modulation

This paper proposes a new digital compensation method for wideband phased array radar using nonlinear frequency modulated signal, which not only reduces the sampling rate of the echo but also obtains the low sidelobe without tapering and high-resolution range profile of the target. At the same time, the time delay differences caused by different array element positions are compensated. Computational results demonstrate both the compensation accuracy and the time-sampling efficiency of the proposed method.
