Wavelet transform is a new applied signal processing technique in recent years, its time-frequency multi-resolution and signal processing performance are analyzed in the paper. A practical ground penetrating radar signal processing method based on wavelet transform is proposed; it contrast with continuous wavelet transform, the experiments indicate that it improves the processing performance of underground...
Radar signal processing system is an important part of vessel traffic services. In order to overcome the shortcomings of traditional analog video system, this paper proposes a design solution for digital radar signal processing system based on DSP and a new method that is a constant false alarm rate algorithm based on wavelet transform. This method can suppress the interference of sea clutter without...
The difficulty for tracking maneuver target is to decide whether a maneuver occurs and when the target begins to maneuver. Since target tracking is a real time problem, the crucial factor is to detect the target maneuver as accurately and quickly as possible. A new approach for the maneuvering target tracking is presented, especially for the target maneuver detection in heavy noise. The algorithm...
An auto-recognition method of ship with low resolution radar is presented in the paper using multi transform technique. The radar target echo is sampled and preprocessed to suppress clutter first. Then characteristic vectors of the target are extracted with FFT transform, Mellin transform, wavelet transform and frame correlation processing. Experiments are carried out for the proposed method with...
