Embodiment Construction
[0030] The embodiments of the present invention are described in detail below, and the embodiments are exemplary and intended to explain the present invention, but should not be construed as a limitation of the present invention.
[0031] The purpose of the present invention is to provide a low-cost solution for evaluating the performance of radar antenna products. For this reason, the present invention proposes a system and method for testing the dynamic performance of radar antennas. The low-cost unmanned aerial vehicle is used as a carrier, which is carried and fixed on the aircraft. The frequency source on the gimbal is used as the tracking target; the radar antenna under test fixed on the ground or the carrier is used to capture and track the UAV during the designed trajectory or remote control flight; the radar antenna system under test is connected to a set of video cameras System, the CCD camera is equipped with a cross cursor and a scale line and is installed on the an...

The invention provides a radar antenna dynamic performance testing system and method. With a low-cost UAV (unmanned aerial vehicle) as a carrier, a frequency source fixed to an airborne PTZ is carried as a tracking target. In the process that the UAV flies according to a design trajectory or remote control, the tested radar antenna fixed to a ground or the carrier is used to carry out capturing and tracking. A tested radar antenna system is connected to a set of video camera system. A CCD camera has a cross cursor and a scale line and is installed on the antenna, and a deviation comparison reference can be provided while a capturing and tracking full process video is recorded. Finally, according to the movement state of the UAV and the position relation between the tracking target and the cross cursor in a record video, the direction deviation of a radar antenna and the dynamic performance of a tested object in a full process are determined. Compared with a traditional testing system, the system of the invention has the advantages of low cost and a simple structure, and a low-cost solution scheme is provided for the independent evaluation of the performance of a radar antenna product by small and medium-sized private enterprises.
Description
technical field [0001] The invention relates to the field of radar antenna control, in particular to a radar antenna dynamic performance testing system and method, which are suitable for the capturing and tracking dynamic performance testing of radar antennas. Background technique [0002] In the early radar antenna system, the test of its capture and tracking performance was usually carried out by a military aircraft carrying a frequency source, or a balloon mounted on a frequency source and towed by a car. The radar antenna was fixed on the ground and was equipped with azimuth and pitch error recording and screen display equipment. Tests that dynamically capture trace performance. With the advancement of technology, radar antenna systems are more and more widely used in various industries and civil fields, and many entrepreneurial enterprises have participated in the development of radar antenna systems. However, because the traditional radar antenna test method has too h...
