In order to make radar target track simulation more realistic in simulation test-bed of C3I system, a new method which utilizes data mining techniques based on historical radar data is proposed. This method includes two stages: The first is “filtering separation piecewise fitting feature clustering". In this stage, the radar historical data is divided into(More)
Repeating decoys (based on DRFM), through main lobe into the radar receiver, realistically simulate real target's echo in both time and frequency domain, and greatly affect radar regular operation of radar. This paper, based on the premise that the actual target is multi-feed radiation and the repeating decoy is single feed radiation, analyzes in theory and(More)
Position estimation for rotating part in high resolution range profile is precondition for rotating part signal separation, when non-cooperation aerial target is observed by inverse synthetic aperture radar (ISAR). Position estimation methods for rotating part put forward in current literatures are not enough robust, when they are applied to real data. In(More)
In the airborne forward looking SAR (FL-SAR), there were a list of antennas along the wing of airplane, which were used to achieve two-dimensional resolution image of scene front the airplane. In order to reduce cost of airborne FL-SAR, it is necessary to cut down quantity of antennas. In this paper, combining the compressed sensing theory, a design method(More)
Repeating decoys (based on DRFM), through the main lobe into the radar receiver, realistically simulate real target's echo in both time and frequency domain, and cause serious threat to radar's search, identification and tracking. At the near distance, angular error caused by target's angular glint is an important noise source and it can be utilized to the(More)
