Rotary phased array radar plot merging method and system, storage medium and equipment

Abstract

The invention relates to the technical field of radars, and discloses a rotary phased array radar plot merging method and system, and the method comprises the steps: receiving echo data of airspace search, and extracting plot measurement information in the echo data with a receiving wave position as a unit; storing the beam position data to a corresponding position of a cyclic beam position cache region according to a row index and a column index of a receiving beam position; wherein the wave position data comprises row and column index information of the receiving wave position, the trace point number in the receiving wave position and trace point measurement information in the receiving wave position; and when the wave position data in the cyclic wave position cache region meets a trace point combination condition, executing a trace point combination processing process. According to the method, a data driving mode is adopted, the plot preprocessing process and the plot data processing process are decoupled, and plot merging can be correctly completed under the condition of different servo rotating speeds and the scene of disordered return of plot measurement results.

Description

technical field [0001] The present invention relates to the field of radar technology, in particular to a method, system, storage medium and equipment for combining rotating phased array radar traces. Background technique [0002] The data processing process of the rotating phased array radar is composed of point track preprocessing and point navigation data processing. The point track preprocessing is responsible for merging the original point track information extracted by the signal processing subsystem, and point navigation data processing is to complete point navigation / Point-to-point association processing, track start processing, etc. In the traditional processing method, the dot trace preprocessing and subsequent processing are closely coupled, and are usually driven by the servo code disc. When the measurement data is returned out of order, the servo code disc cannot be used as the basis for starting the data processing process; the data processing process is affec...

Problems solved by technology

In the traditional processing method, the dot trace preprocessing and subsequent processing are closely coupled, and are usually driven by the servo code disc. When the measurement data is returned out of order, the servo code disc cannot be used as the basis for starting the data processing process; the data processing process is affected by the measurement results. Loopback driven; therefore, traditional processing methods cannot correctly perform dot-trace merging in scenarios where loopbacks from the signal processing subsystem are out of order
