Synthetic Aperture Radar Interference And Interference Performance Evaluation Studies

Synthetic Aperture Radar (SAR) is a kind of active microwave imaging radar. It can all-weather, all-day and timely get ground image of wide region and has fine penetrability to vegetation and ground. SAR is pretty important to resources exploitation and military reconnaissance and has been widely used in diverse fields of civil and military.This dissertation simulates SAR point target imaging with Range-Doppler (R-D) Algorithm based on analyzing SAR imaging theories and algorithms.Based that, we analyze the technology of SAR active jamming and the methods of jamming effectiveness evaluation, research suppression jamming and deception jamming systemically. And we simulate several jamming modalities of suppression jamming and deception jamming, which proves its validity and correctness. We then use three different methods to evaluate the jamming effectiveness, analyze the result of the simulation.The main work and achievements are as following:1. Simulates SAR point target imaging with R-D Algorithm;2. Using four different jamming modalities to simulate suppression jamming, and get some significative conclusions;3. Simulates points deception jamming simply;4. Analyzing the methods of SAR Jamming effectiveness evaluation systemicly .Using three methods to evaluate the jamming effectiveness, analyze the result of the simulation, and it is validity and correctness.
