Abstract

A method for the evaluation of passive millimeter wavelength sensors for the detection of point targets is described. The basis of the performance evaluation is the determination of signal-to-noise ratio where noise includes both thermal noise and background clutter. Because passive millimeter wavelength sensors depend on target contrasts against background, similar to detection of point targets by visible and infrared wavelength sensors, the method is an adaptation from that used in the evaluation of visible and infrared wavelength sensors. Background clutter as well as thermal noise are described by power spectral densities. Because of the limited amount of data on power spectral densities of backgrounds at millimeter wavelengths, a power spectral density was derived. Methods used in visible and infrared sensors for signal-to-noise ratio enhancement are discussed for adaptation to passive millimeter wavelength sensors.
