| Abstract: | This paper analyzes the influence of aperture fill time on phased array radar signal, which includes signal time shift, amplitude weighting and energy loss, presents a digital compensation method o{ aperture fill time for phased array radar based on signal processing method, which can compensate the signal time shift and amplitude weighting caused by aperture fill time. Compensation simulation of aperture fill time for typical array shows the correctness and effectiveness of the proposed method. |
