| Abstract: | A Scheme of radar image for achieving high range resolution is presented.The high resolution is achieved by processing a carrier with frequency kept constant wrthin each pulse ,but frequency shifted from pulse to pulse by a fixed frequency step size. According to the requirement of engineering design,the effects of system errors including frequency error and the error from the quadrature demodulation are analysed and experiment simulated with computer.A series of simulation results and quantitative relationships with some error are given. |
