Radam Phenomena of Tracked Vehicles.

The backscatter power density spectrum from the track of a tracked vehicle is investigated in this report. The major contributors to the spectrum are modeled as a rotating cylinder and a uniformly moving linear array. Both spectra consist of discrete spectral lines. The former peaks around the incident angular frequency omega sub 0, while the latter peaks around omega sub 0 omega sub Dcos psi, where omega sub D is the Doppler angular frequency and psi is the angle of incidence measured from the direction of the array velocity.
