Sar Class Clutter Of Technical Software And Hardware Design

Synthetic Aperture Radar (SAR) is a kind of active microwave imaging radar. It can all-weather, all-day and timely get ground images of wide region and has fine penetrability to vegetation and ground. SAR is pretty important to resources exploitation and military reconnaissance. High-resolution SAR has been widely used in diverse fields of civil and military because of its high-reselution, strongly anti-jamming, and anti-destructive abilities.This dissertation analyses the back ground clutter's characteristic of SAR and the serious influence to SAR target detection and classification. Based on analyzing jamming methods in existence such as noise jamming and cheat jamming, and the anti-jamming ability of high-resolution SAR, the author puts forward a new matching jamming which is time , frequency and dopple fields multidimensional-matching-overcast similar clutter's jamming. Through the zero memory nonlinearity (ZMNL) method, generates of the correlated log normal, weibull-distributed clutter vectors.The author researchs the jamming theory based on the leading of parameters, confirmed this method to have the good jamming effect regarding SAR through the simulation experiment and quality evaluation of SAR image. Then evaluate the counter- suppression ability of similar noise jamming toward the anti-jamming methods of SAR, through the simulation experiment.At last the author analyzed the jamming ability of similar noise jamming to the moving target indication (MTI) and carried on the confirmation through the simulation experiment.Finally, the author has carried on software and hardware design of the similar clutter baseband signal production based on the TMS320C6414DSP processor. and confirmed the design feasibility through the simulation experiment.
