Recovering-Resampling Estimation for Multi-Targets in Nonlinear FSCW System

摘要：

In this paper, the multi-targets distance estimation in nonlinear Frequency-Stepped Continuous Wave (FSCW) system is studied, and an estimation method based on the recovering-resampling is proposed. Theoretically, this method can solve the target estimation problem under nonlinear frequency modulation using the software algorithm instead of the complex, expensive closed-loop real time correction method, thus the cost and difficulty of system implementation is greatly reduced. The simulation results show that the recovering-resampling method can overcome bad effects on the accuracy and resolution of targets detection caused by the non-linearity. In addition, the disadvantage of this method is also analyzed.
