Embodiment 1

[0055] Embodiment 1. This embodiment discloses a method for real-time identification of non-cooperative targets in the sea clutter measurement area of ​​shore-based radar, including the following steps:

[0056] (1) Build a data receiving system based on AIS:

[0057] Such as figure 1 As shown, the data receiving system includes a computer (desktop or laptop), AIS, and database server installed with a non-cooperative target real-time recognition unit. The non-cooperative target real-time recognition unit is used for the visualization of the radar position and the radar beam irradiation area, and the AIS-based Visualization of non-cooperative target status information and database server storage management. The computer receives the non-cooperative target status information sent by AIS in real time, and stores the non-cooperative target status information in the database server through the non-cooperative target real-time identification unit, and visualizes it in real time. AIS is u...

Abstract

The invention discloses a real-time identification method for a non-cooperative target in a shore-based radar sea clutter measurement area. The method comprises the following steps: (1) constructing adata receiving system based on an AIS(Automatic Identification System); (2) calculating a sea clutter measurement radar beam irradiation area; (3) establishing a non-cooperative target identificationmethod; and (4) determining whether a non-cooperative target is in the radar beam irradiation area. According to the method based on the AIS, the AIS longitude and latitude information provided by the non-cooperative target is used according to the irradiation range of radar wave beams, the non-cooperative target is identified in real time, and state information including time, latitude and longitude of the non-cooperative target can be displayed and extracted in real time, and further stored and managed.

Description

Technical field [0001] The invention belongs to the field of target recognition in a sea clutter measurement area, and particularly relates to a real-time recognition method for non-cooperative targets in a shore-based radar sea clutter measurement area in the field. Background technique [0002] For the early warning radar, the backscattering of the radar signal from the sea surface severely limits its ability to detect aircraft, missiles, ships, and other targets that are in the same radar resolution unit as the sea surface, so it needs to be carried out in different sea conditions. , Research on sea clutter characteristics under different radar operating parameters (frequency, polarization, resolution unit, incident angle, etc.). However, non-cooperative targets (such as cargo ships, fishing boats, etc.) may appear in the test area of ​​the sea clutter measurement radar. The interference of these non-cooperative targets may affect the accuracy of sea clutter characteristics re...
