Velocity Measurement and Ranging Method with Range Aliasing for LFMICW Radar
ieee asia pacific conference on synthetic aperture radar(2019)
摘要
Linear frequency modulated interrupted continuous wave (LFMICW) technique is developed to solve the isolation of LFMCW radar. However, there is a range aliasing problem where apply the LFMICW radar for high-resolution and long-range situation. The range aliasing will bring false targets into the range profile, which makes it difficult to detect the target. In this paper, a method of staggered interrupted frequency square wave to eliminate range aliasing is adopted and applied to the MTD-frequency domain pairing velocity measurement and ranging method for the LFMICW radar. The effectiveness of the method is verified by simulation.
