Method of SAR image despeckling based on local adaptive processing;

In the environments of information war,using Agent technology as cutin point,the prototype of remote arming testing information adaptive processing center has been studied,the technology realizations and functional requests of each(Agent′s) of the prototype has also been analyzed.

Firstly intellectual network filtration system work flow was studied,then systematic design of intellectual network information filtration system was given and each module was analyzed,finally three modules of network data processing,text data processing and adaptive processing were performed detailed study.

Adaptive digital beam forming(ADBF) has improved performance in severe clutter and against multiple sources of interference, so it is the key technology of the modern radar system.

The technology of adaptive signal processing is very important in the field of radar,communication,sonar,image processing,computer vision,prospect for earthquake,biomedicine,vibration project,etc.

As the features of leak signal vary with the materials,sizes,inbuilt conditions,pressure and flow of pipes,and bursting interferences are inevitable where detection operates,so the adaptive signal processing and the wavelet analysis method are deployed to estimate the time delay and locate the leak.

In a denoising simulation experiment with the mean square error criterion, these algorithms are compared to the classic algorithms of adaptive signal processing, such as LMS and RLS.

Unscented space-time adaptive processing algorithm

Time-frequency analysis can improve the performance of space-time adaptive processing for non-stationary interference.

Traditional space-time adaptive processing algorithms can be implemented in the airborne radar system by changing both the amplitude and the phase of weights associated with each array element.
