ABSTRACT:
A method and apparatus for measuring the extent of camouflage applied to a arget is disclosed. The apparatus includes a direct electronic Fourier transform device responsive to first and second conditions of camouflage of a target for producing spectra signals of first and second limited Fourier transforms, respectively. Each of the spectra signals has a plurality of amplitude and principal frequency components, and a base clipper circuit is provided for deleting the spectra signal amplitude components below a given value. A radio frequency voltmeter and a first analog-to-digital converter cooperate to produce digital signals corresponding with the magnitude of the amplitude components. Similarly, a radio frequency frequency meter and a second analog-to-digital converter cooperate to produce digital signals corresponding with the principal frequency components. A control device controls the operating sequence of the digital signal producing devices for subsequent spectra signals and a memory stores the first and second digital amplitude and principle frequency signals. The first and second amplitude signals are compared in a comparator, thereby to indicate the difference between the extent of camouflage of the target in the first and second conditions.
