Numerical Modeling of the Airborne Radar Signature of Dismount Personnel in the UHF-, L-, Ku-, and Ka-Bands

Abstract

This technical report presents numeric computations of the radar cross section (RCS) of a human body placed on top of a ground plane, as seen by an airborne radar. The simulated data was collected in four frequency bands, at low microwave frequencies (UHF- and L-bands), and high microwave frequencies (Ku- and Ka-bands). For the low frequency bands we used the Finite Difference Time Domain (FDTD) modeling technique, whereas for the high frequency bands we employed the Xpatch radar signature software. The results are presented as radar cross section (RCS) over a large range of azimuth and elevation angles. In general, we noticed a relatively small variation of the human body average RCS over a wide range of frequencies, spanning the interval from the UHF- to the Ka-band.
