This paper discuss on Forward Scatter Radar Cross Section (FS-RCS) of different target specifications. A simulation analysis on target with different specifications to Radar Cross Section (RCS) for Forward Scatter Radar was conducted. Materials used for the target are based on the features of the actual car. It is observed that the side lobe spectrum is more visible as the frequency is higher for the different characteristic of a target. Slight changes were made on the target which resulted in different readings of RCS.
