Example Embodiment

[0035] The invention is further illustrated in connection with the accompanying drawings and examples, and the present invention includes, but is not limited to the following examples.

[0036] The present invention is targeted for the target data reported by the gun session, and the target data reported by the radar is submitted, and the false target is removed, and the real data is obtained. Docked the target data received, the data is fitted to the secondary curve of different dimension coordinate points, resulting in correlation coefficient, residual, speed, and acceleration value, compares the actual projectile threshold, eliminating false targets Information, report the real projectile target.

[0037] Taking the target data reported by the radar front end in a model reconnaissance calibration radar blast reconnaissance mode as an example, the format is a timestamp, a position sine value, a pitch sine value, a distance, and the present invention includes the following steps:...

Abstract

The invention provides a radar detection projectile false target processing method which comprises the following steps of: firstly, modeling each dimension through a motion track of a target, and judging whether a current projectile is in a reconnaissance or calibration mode through a flight track; then correlating the model with the actual trajectory, wherein the correlation between the trajectory of the false target and the model is very small, the correlation between the real target and the model is high, and if the models are highly similar, the characteristic speed and acceleration of the projectile are judged. According to the invention, projectile targets can be correctly identified, and false targets can be effectively eliminated. The recognition method is used for processing target data of a signal processing end, clutter false alarms and projectile targets can be well distinguished, and therefore reporting of false targets is greatly reduced for the radar of the model.

Description

technical field [0001] The invention relates to a target recognition method, which is suitable for the field of radar detection. Background technique [0002] The targets output by the signal processing end include real targets and false targets. How to better report real targets and effectively eliminate false targets is an important task. [0003] At present, the ability of artillery position reconnaissance and calibration radar to identify false targets is uneven, and there are problems such as high false alarm rate in the environment, affecting the radar's recognition of projectile targets, and misidentifying false targets as projectile targets. In this case, it is necessary to improve the recognition probability of projectiles and eliminate false targets in the data processing stage to achieve the purpose of reporting real targets. [0004] In the past, a one-dimensional data processing method was generally used to eliminate false targets, and only a single judgment wa...
