Embodiment Construction
[0059] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0060] see figure 1 , the present invention provides a real-time Doppler beam sharpening super-resolution imaging method for airborne radar, which is realized by the following steps:
[0061] S1. Acquire current coherent process interval (Coherent process interval, CPI) echo signals, and perform pulse compression and distance walking correction processing on the echo signals.
[0062] In this embodiment, the schematic diagram of the geometric model of the airborne scanning radar is as follows figure 2 As shown, the parameters of the radar platform are shown in the following table (1), and the original scene graph of the target is shown in image 3 As shown, the set rhombic array point target proves the effectiveness of the method of the present invention.
