Kinematic parameters extraction from a single node forward scatter radar configuration

This paper focuses on the exploitation of a single node Forward Scatter Radar configuration for the estimation of the kinematic parameters of targets following a linear trajectory. Accordingly, the target signature extracted from a square law detector followed by a DC removal filter is exploited. A four step processing technique is proposed for the estimation of the main target parameters encoding Doppler rate and derivative of the Doppler rate that are exploited for the extraction of the target motion parameters. In particular, the target velocity and the baseline crossing angle are both estimated under the assumption that the baseline crossing point is known. The proposed approach is assessed firstly through synthetic data. Then, experimental data collected by a passive Forward Scatter Radar exploiting FM signals as waveform of opportunity are processed to confirm the effectiveness of the proposed technique.
