Forward-looking Imaging Based on Real Beam Scanning Non-complete Data Deconvolution

Forward-Iooking high-resolution imaging of airborne radar can obtain the high-resolution map of the front of the fighter and detect the battlefield in real time, so as to complete the accurate tracking of the enemy's movement and the military target. In this paper, the problem of forward-looking imaging is discussed, the key technology of trajectory direction scene imaging is studied, and forward-looking imaging based on real beam scanning non-complete data deconvolution is proposed. Firstly, the interpolation is used to expand the radar echo data to get the approximate complete convolution data, then the frequency domain image effect is filtered by the low-pass filter, and finally the deconvolution operation is carried out. Theoretical analysis and simulation results show the feasibility and effectiveness of the proposed method.
