MTD and Range-Velocity Ddcoupling of LFMCW Radar
LFMCW雷达运动目标检测与距离速度去耦合

To solve the problem of Moving Target Detection (MTD) and range-velocity decoupling in LFMCW Radars, a method combining MTD with frequency domain pairing is proposed. The method realizes detection and classification of moving targets with different ambiguous velocities via MTD in order to simplify the spectrum of beat signal, then eliminates moving target's range-velocity coupling based on the symmetry of the Doppler shift between positive and negative frequency sweep in triangular frequency modulation continuous waves. The effectiveness of the method is demonstrated by simulations.
