Research on Two-Channels Pulse to Pulse Frequency Shifting Outdoor RCS Measurement Radar
双通道脉间变频外场RCS测试雷达的研究

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-profile’s distortion and frequency is analyzed. A method to calculate the target’s 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 target’s radial velocity effect on range profile can be corrected. The method is used to process the real outdoor measured data. The amplitude of the target’s imaging is boosted and the major lobe of the target’s imaging become narrower after being corrected.
