Abstract: Design of two-channels high-range-resolution pulse to pulse frequency shifting RCS outdoor measurement radar is researched. A waveform design and a system realization method are presented. The numerical relationship between range-profiles distortion and frequency is analyzed. A method to calculate the targets radial velocity by the measurement results is discussed based on the architecture that the radar can measure the target on two different frequency band at the same time. The targets radial velocity effect on range profile can be corrected. The method is used to process the real outdoor measured data. The amplitude of the targets imaging is boosted and the major lobe of the targets imaging become narrower after being corrected.
