Abstract

The invention discloses a meteorological detection and target monitoring method based on azimuth rotating phased array radar. The method comprises the following steps: enabling a meteorological detection period to comprise N target monitoring periods that coincide with a radar azimuth mechanical rotation period; when performing the ith target monitoring in the meteorological detection period, allocating dwell times for each azimuth, and adopting a time division multiplex scanning method for each azimuth, that is, transmitting target monitoring scanning beams from the first beam position to theMth beam direction for each azimuth, and transmitting a meteorological detection scanning beam with the degree ai of a pitch angle for each azimuth, wherein the cumulative number of degrees ai of pitch angles of the meteorological detection scanning beams in the meteorological detection period satisfies a complete meteorological scan. The method not only effectively solves the problem of the fusion of the target monitoring and the meteorological detection, but also solves the technical problem that the target is easily lost due to the meteorological detection cycle occupying the target monitoring period.

Description

technical field [0001] The invention relates to the technical field of phased array radar, in particular to a weather detection and target monitoring method based on azimuth rotation phased array radar. Background technique [0002] The azimuth-rotating phased-array radar has the advantages of low cost and high flexibility. The azimuth-rotating phased-array radar is used to realize the functions of weather detection and target monitoring at the same time, so as to greatly improve the practical performance of the radar. However, the target monitoring function requires a high scanning rate of the radar, and the weather detection function requires a long enough dwell time of the radar. Therefore, if the azimuth-rotation phased array radar is to realize the weather detection and target monitoring functions at the same time, it is necessary to ensure the design of the dwell time At the same time, it takes into account the requirements of target monitoring and weather detection. ...
