A new high precision Range Vernier method for phase-coded radar

Range measurement with high precision is of profound significance to improve the ability of detection and discrimination for radar. This paper addresses the range measurement of midcourse targets with high velocity based on phase-coded radar. Firstly, the principle of Range Vernier is introduced, and the characteristics of the phase-coded signal are analyzed. And then, a new method for high precision Range Vernier is proposed to process the radar echoes, in which matched filter and phase ambiguity unwrapping algorithm are designed specially. Finally, the simulations demonstrate the performance of the method.
