The key problem of Forward Scattering Radar (FSR) utilization is the high level of surface clutters. EM wave propagation analysis is used to evaluate the sea clutter level in FSR and a brand new subclass of FSR is proposed, i.e. Ultra Wideband FSR which has essentially higher immunity to sea clutter. NB FSR is a special bistatic radar configuration, where the bistatic angle, is around 180bβ 0 . In this paper we assume that the radar central (carrier) frequency is around 10 GHz, i.e. traditional for maritime applications X-band. In contrast to other radar systems, including bistatic, the received signals in FSR are not target reflections, but the shadow of the emitted electromagnetic (EM) energy. This shadow is created as a target’s presence between the transmitter and the receiver which blocks the EM waves travelling from the transmitting antenna towards the receiving antenna. A typical FSR for surface targets Ta detection is shown in Fig.1.
