Abstract

The validity of the extension of R-meter theory advanced by W. H. Lob has been tested experimentally by laboratory simulation of both radar signals and typical radar signal processing equipment. The experimental results show the theory to be valid, subject to restrictions on signal-to-noise ratio and crossing-rate-to-sampling-rate ratio, for both linear and logarithmic signal amplification. The restrictions can be attributed to limitations of the experimental technique and to aliasing. It is concluded that Lob's theory should be used to determine Doppler power spectrum variance in lieu of conventional R-meter theory.
