Acceleration and Velocity Estimation of Targets in Bistatic Multi-Frequency FMCW Radar
双基地多载频FMCW雷达目标加速度和速度估计方法

The bistatic multi-frequency FMCW radar uses sparse-array to transmit the FMCW signals of multiple carrier frequencies, and an array to receive the echoes. The Doppler spectrum is widened because the Doppler signals are modulated by acceleration and velocity of maneuvering target, which leads to the degeneration of radar's detection performance. The signal model of bistatic multi-frequency FMCW radar is analyzed in this paper. A method using Discrete Polynomial-phase Transform(DPT) and phase difference is p...
