Problems solved by technology

When testing the performance of the antenna, it is necessary to use measuring instruments to build a test system in the microwave anechoic room. An additional two-dimensional turntable is required to test the single-pulse performance of the antenna. Rotate the antenna to obtain the difference channel ratio and channel normalization value at different angles. Using the above When the traditional method evaluates the single-pulse performance of the antenna, it faces the following problems: the accuracy of the two-dimensional turntable may not meet the angle measurement accuracy of the narrow beam antenna, and the angle information of the two-dimensional turntable cannot be synchronized with the antenna difference channel ratio and channel normalization information

Abstract

The invention discloses an antenna monopulse performance evaluation method under a complete machine condition, and the method comprises the following steps: firstly, positioning the position of a target relative to a radar, then correcting the deviation between the zero depth of a difference channel of an antenna of the radar and the main beam of a sum channel, obtaining the normalization information of the difference channel and the sum channel of the antenna at different pointing angles, analyzing the normalized information to obtain an evaluation result of the monopulse performance of the antenna. According to the method, the antenna is controlled to move through a control mechanism of the radar according to the condition of the whole machine, normalized information at different angles is obtained by adopting a signal power estimation algorithm and a data fusion algorithm, and the monopulse performance of the antenna is rapidly evaluated.

Description

technical field [0001] The invention relates to the technical field of monopulse radar tracking, in particular to an antenna monopulse performance evaluation method under the condition of a complete machine. Background technique [0002] Antenna monopulse performance determines radar tracking performance. When testing the performance of the antenna, it is necessary to use measuring instruments to build a test system in the microwave anechoic room. An additional two-dimensional turntable is required to test the single-pulse performance of the antenna. Rotate the antenna to obtain the difference channel ratio and channel normalization value at different angles. Using the above When evaluating the single-pulse performance of antennas in traditional methods, the following problems are faced: the accuracy of the two-dimensional turntable may not meet the angle measurement accuracy of the narrow beam antenna, and the angle information of the two-dimensional turntable cannot be syn...
