An Efficient Plot Fusion Method for High Resolution Radar Based on Contour Tracking Algorithm

الملخص EN

With the development of radar system, the problem of enormous raw data has drawn much attention.

A plot fusion method based on contour tracking algorithm is proposed to detect extended targets in a radar image.

Firstly, the characteristic of radar image in complex environment is revealed.

Then, the steps of traditional method, region growing method, and the proposed method are introduced.

Meanwhile, the algorithm of tracking the contour of an extended target is illustrated in detail.

It is not necessary to scan all the plots in the image, because the size of target is considered in the proposed method.

Therefore, the proposed method is much more efficient than several existing methods.

Lastly, the performance of several methods is tested using the raw data of two scenarios in real world.

The experiment results show that the proposed method is practical and most likely to satisfy the real-time requirement in various complex environment.
