Study On The Clutter Tracking Algorithm For Airborne PD Radar

The main function of radar is target detection in the background clutter.The effect of clutter to the automatically detecting system is one of most important problem which could not ignore in the radar design. The clutter tracking technic supply the warrant for the choice of CFAR detecting algorithm by the character clutter tracking and localization. It has a active significance to improve the detecting performance of radar. Combined with the Foundation Research (Avigation science fund 04D52032)"study on CFAR detecting expert system base on clutter tracking".This paper study the fractal technic and snake algorithm on the application of clutter tracking. It proved that the method was effective by the algorithm which adapt to the real and simulant clutter data.This paper introduce the intelligentized and integrative research on the radar detecting in and abroad.It also introduce the clutter tracking latterly.This paper analyze the basic character clutter and the clutter model. It study a simulation algorithm of airborne PD radar and carry out the the clutter sample of different distributing, The location of character clutter in detecting and the relation of radar system parameter are research in this paper.This paper introduces principle of fractal and the Mandelbrot fractal theory.It analyze the fractal character and study the mltifractal for the clutter tracking. In according to the rage which follow the q on point fractal dimension and region fractal exponent .We confirm the prepreerence multifractal high moment, Combining the clutter feature of PD radar and novel multifractal approach, The mainlobe clutter tracking come true.This paper study the greedy snake algorithms for the clutter tracking.It introduce the energy function of basic snake model and analyze the different kind of snake discrete energy function.It study on the method which use the pretreatment combining the sobel and grads arithmetic operators.The astringency of snake external energy was satisfied. This paper analyze the influence of tracking precision and running time for the preliminary border width, It also study on the tracking effect of different distributing and intensity.It is important to the next work.The tag of this paper makes a summary of research and gives expectation on research future.
