This paper is devoted to the estimation of target motion parameters with a forward scatter radar (FSR). To provide an upper bound for the estimation performance, a closed-form expression of the Cramér-Rao lower bound (CRLB) is provided for the main target signal parameters, namely Doppler rate, baseline crossing instant, and main lobe width parameter of the target amplitude modulation pattern.

The focus of this work is on the estimation of the motion parameters of moving targets by means of a dual receive antenna Forward Scatter Radar (FSR) configuration. For this purpose (i) the Doppler signature spectrogram for the single node FSR configuration and (ii) the time delay technique based on the cross-correlation between the signals acquired by a FSR system comprising two different receivers, are both analysed for the joint estimation of the baseline crossing point and of the cross baseline velocity.

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.
