Embodiment Construction

[0019] A method for simulating the echo of a marine radar target, comprising the following steps:

[0020] Step 1: Input the collected true north signal, azimuth increment code, main pulse signal and target distance, moving speed and target azimuth parameters of the radar to be simulated into the display and control track simulation module; the display and control track simulation module includes DSP, FPGA, SDC / RDC and additional circuits, in which DSP calculates the track information of the simulated target according to the input requirements of the simulated target; FPGA, SDC / RDC receive the true north signal and azimuth incremental code and calculate it Azimuth information, the track information and azimuth information of the simulated target after the solution are sent to the DDM module;

[0021] Step 2: Send the output signal of the radar to the input frequency conversion module. After the input frequency conversion module receives the radar signal, it divides the radar s...

Abstract

The invention provides a marine radar target echo simulation method, which comprises the following steps: 1) inputting collected due north signals, orientation increment codes and main pulse signals of a radar to be measured and target distance, moving speed and target orientation parameters to be simulated into a display control track simulation module, wherein the display control track simulation module comprises a DSP, an FPGA, an SDC/RDC and additional circuits. The DSP is used for calculating track information of a simulation target according to the input simulation target requirement; and the FPGA and the SDC/RDC receive the due north signals and the orientation increment codes and then, calculate orientation information, and send the calculated track information and the orientationinformation of the simulation target to a DDM module. The method simulates the detected target echo signals of a marine radar through a computer, and provides known simulation target information to the radar to be measured, thereby realizing detection of the radar to be measured under no real target. The simulated target echo signal is very close to the real information, thereby solving the problem of detection of shoreside of the radar.

Description

technical field [0001] A method for simulating the echo of a ship-borne radar target relates to the simulation test of the ship-borne radar. Background technique [0002] As the main electronic equipment on the ship, marine radar is mainly responsible for the ship's early warning, target search and tracking, weapon control, navigation and other important roles. Therefore, there are higher and higher requirements for the maintenance of radar. Due to the limitations of the use site and environment, the radar cannot be provided with a real target. Therefore, to test the functional performance of the entire radar machine on board, the radar simulation signal source must be used to simulate the echo of the radar target for testing. [0003] The existing technologies mainly have the following shortcomings: [0004] 1. At present, the standard signal source can only simulate and compare several single signal waveforms. The signal characteristics are very different from the echoes...
