Radar target classification recognition algorithm

Abstract

The invention discloses a radar target classification and recognition algorithm. The algorithm is characterized by comprising the following process steps: continuously acquiring radar track point data; performing data cleaning on the acquired radar track point data; storing the received track points according to track batch numbers; each time a new track point is reached, adding the new track point into the track queue of the batch number; storing feature data formed by the new track into a feature data queue; if the track has more than two track points, taking a new track point as a starting point and ending, and taking a previous track point as a starting point; storing feature data formed by the tracks of the two points into a feature data queue; if the track has more than three track points, taking a new track point as a starting point and an ending point, and reversing two track points in time; storing feature data formed by the three-point track into a feature data queue; the stored calculation feature data are sent to a decision tree classifier; and the decision tree classifier outputs the type of the target.

Description

technical field [0001] The invention belongs to the technical field of electronic information, in particular to a radar target classification and identification algorithm. Background technique [0002] The radar transmits electromagnetic waves into the air through the transmitting antenna. During the propagation of the electromagnetic waves, they encounter objects that can reflect the electromagnetic waves, and part of the electromagnetic waves are transmitted back to the receiving antenna of the radar, thereby entering the receiver of the radar. The electromagnetic waves reflected to the radar receiving antenna are called radar echoes. If the echo strength of the radar is strong enough, the radar receiver can detect it using signal processing technology, and then display it in the form of bright spots or waveforms on the radar screen. Using the radar display, the radar operator can see the radar echo from the radar display; [0003] The radar echo carries distance informa...
