Embodiment Construction
[0042] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.
[0043] Such as figure 1 As shown, a method for calculating the main distribution of the main and side lobes ground-sea clutter under radar down-sight tail detection, including the following steps:
[0044] S1. According to the strength of the gain in each direction of the radar downsight and rear detection beam, determine the corresponding area of the main distribution of the main and secondary lobes and sea clutter.
[0045] Step S1 specifically includes:
[0046] S1.1. Establish the reference coordinate system and the platform coordinate system respectively, such as figure 2 shown;
[0047] Among them, the origin of the reference coordinate system is set on the ground / sea surface, the X axis is the north direction, the Y axis is the sky direction, the Z axis is the east direction, and the position of the ...
