As we all know, radar radiometric calibration is a very important research in Synthetic Aperture Radar (SAR). The accuracy of radiometric calibration is always the focus of all the researches. In this paper, the authors make a thorough study on radiometric calibration, and put forward a new model of radiometric calibration. Based on the new model, a new method of vectors of Discrete Cosine Transform...
Signal separation plays a very important role in radar signal processing. The separation of radar signal and the background signals has great influence on radar signal processing. The traditional method has little efficiency when the background signal is nearly the same as the radar signal. Therefore, a more efficient method is needed. This paper is devoted to design a new type of mismatch network...
The use of mismatch network to modulate the retransmitted signal of an active radar reflector (ARR) can separate the reflected ARR signal from background signals effectively. The effect of separation depends on the characteristics of the mismatch network. In order to achieve the best separation between the reflected ARR signal and background signals, we need to make optimization design of mismatch...
