Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Using the hardware platform that radar generally has, the target simulation process is as follows: figure 1 shown. The following is figure 1 Instructions for the hardware used in:

[0024] Waveform generation: Waveform generation mainly generates the intermediate frequency waveform signal required by the transmitting module. The form and duration of the signal are controlled by the waveform code sent by the signal processing system. Waveform generation generates the required analog signal in real time according to the waveform code information sent by the signal processing system.

[0025] Calibration channel: The calibration channel outputs a test signal to the calibration network, which is sent to the receiving end of each T / R component through the calibration network, and the system can calibrate the receiving channel of the T / R component; at the same time...

Abstract

The invention relates to the technical field of radars, in particular to a target simulation method based on a correction network. The target simulation method simulates a target position, distance, height, speed, range and static target from a source. A simulation target generated by the method is more realistic than a simulation target generated by a terminal monitoring and can be used for receiving data base file (DBF) validation, maximum tolerated dose (MTD) validation, a small target detection capability validation and tracking capability validation. The target simulation method comprises steps of simulation target decomposition, target trace point appearing time calculation, target trace point distance simulation, target trace point height simulation, target trace point position simulation, target trace point doppler frequency simulation and target trace point range simulation. The target simulation method can reduce development cost of the radars, can be used for simulating training after being loaded along with devices, reduces staring time, prolongs service life of the radars, and reduces training cost.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a method for simulating a target based on a correction network. Background technique [0002] In the performance debugging of the radar prototype development stage, the debugging and verification of some indicators require the cooperation of target information. The use of aircraft for actual flight is not only difficult to coordinate, but also greatly increases the development cost. [0003] Existing target simulators need to add dedicated hardware devices, which increases the manufacturing cost of the target simulator. For example, the Chinese utility model patent "a synchronous high-frequency ground wave radar target analog signal source device" (application number: CN200820192242.5), which constructs a hardware platform based on software radio design ideas; the Chinese invention patent "uses carrier to extract video Radar Outfield Target Simulator with Storage Method" (Applicat...
