Method for simulation of ship radar target ship echo 2D imaging

Abstract

The present invention relates to a method for simulation of ship radar target ship echo 2D imaging. The method comprises the steps of: setting radar echo imaging parameters, and simulating radar echoin a scanning line mode; constructing a ship navigation simulation unit to provide a ship simulation motion state through a multicast communication mode; performing radar simulation data preprocessing; solving the relative position relation between each point on the radar scanning line and the target ship to determine the amplitude of each point on the scanning line; and performing radar echo imaging information visualization. The ship navigation simulation unit and the radar echo simulator are designed to send simulated target ship echo imaging information in real time through network communication, a man-machine interactive interface is arranged to customize the number, the size, the position and the posture of the echo imaging and flexibly customize the dynamic echo imaging signals so as to provide universal verification imaging test signals for a ship and bridge radar display-and-control station.

Description

technical field [0001] The invention relates to a 2D imaging method, in particular to a 2D imaging method of a target ship echo for simulating a marine radar, and belongs to the technical field of communication information simulation. Background technique [0002] Marine radar is a target detection tool installed on a ship to monitor a certain area around the ship in real time. It provides an important source of information for tasks such as ship positioning, auxiliary obstacle avoidance, and dangerous situation estimation. Therefore, it is usually equipped on the bridge. The radar display console for real-time display of echo imaging information provides ship control personnel with imaging information of surrounding target ships, islands and other objects, especially the target ship is in a state of dynamic changes in real time, and its imaging information is extremely important to the ship. In the absence of hardware facilities such as radar antennas, it is usually impossi...

Problems solved by technology

However, the previous studies have the following problems: On the one hand, the above echo imaging often carries out mechanism analysis and modeling from the perspective of radar digital signal processing, and cannot directly provide information such as the longitude, latitude, and heading of the target ship for the radar display console On the other hand, it is difficult to quickly and flexibly provide real-time indicators such as scanning period and physical distance corresponding to the scanning point for the radar display console with the above radar signal simulation method
