Quantitative Measurements of Radar Echoes from Aircraft. 7. B-36 and F-86 Spectrums

Abstract

Spectral analyses have been made of the radar echoes of B-36 and F-86 aircraft for aspects near head-on, broadside, and tailward. In the B-36 echo there are discrete frequency components arising from propeller modulation, except at broadside aspect, where the relative effect of the propellers is minimum. The F-86 spectrums are similar for all three radar frequencies, the spectrums tending to be shifted to higher fluctuation frequencies as radar frequency increases.
