[0002] The ground object echo is an important data displayed by the radar. The ground object echo generated by the traditional radar installation or simulation training equipment ground object generation method cannot change with the movement of the radar platform, and the echo intensity is not high in fidelity. Issues such as limited geographical areas have seriously affected the improvement of the capabilities of radar operators, and have also greatly reduced the applicability of radar installation or simulation training equipment

The invention discloses a ground clutter rapid generation algorithm based on multi-platform radar. The algorithm includes: the step 1: coordinate transformation of elevation information; the step 2: gradient calculation relative to the radar wave beam; the step 3: calculation for intensity of ground clutter; and the step 4: the ground feature display step. The ground clutter rapid generation algorithm based on multi-platform radar utilizes the geographic elevation information and the relevant algorithm to rapidly calculate the required radar ground clutter which is used for ground feature displaying, and can be suitable for radars of multi platforms, such as a ship and a shore, and can be used in a radar real device or a radar simulation training device to enable the radar real training device to quickly generate lifelike ground clutter which can be identified by the real device, and at the same time to enable the radar simulation training device to generate ground clutter which is identical to the practical situation.
Description
technical field [0001] The invention relates to the technical field of radar, in particular to a rapid generation algorithm of surface and object echoes suitable for multi-platform radars. Background technique [0002] The ground object echo is an important data displayed by the radar. The ground object echo generated by the traditional radar installation or simulation training equipment ground object generation method cannot change with the movement of the radar platform, and the echo intensity is not high in fidelity. Issues such as limited geographical areas have seriously affected the improvement of the capabilities of radar operators, and have also greatly reduced the applicability of radar installation or simulation training equipment. Contents of the invention [0003] The existing technology is difficult to meet people's production and living needs. In view of the above problems, the present invention aims to provide a rapid generation algorithm for ground object e...
