In order to reduce the underwater ultrasonic image speckles and to enhance the image characteristics, an anisotropic diffusion model is established based on the wavelet transform in this paper. At the same time, it also provides the steps of the algorithmic architecture and analyzes the key links of the model during its application. Two-check experiments(More)
There are some serious interference signals on the airborne radar surveillance polarization receiver during working, which are caused by local electronic equipments. By extracting frequency polarization features, the simultaneously arriving signals of radar surveillance and interference can be polarization separated, and having a high accuracy. At the same(More)
