System Design For A Staring Mosaic Sensor
Abstract
In this paper analytic and numerical methods are presented for the design of a staring mosaic sensor system. The calculations are simplified by using the properties of two-dimensional Fourier transforms. The methods permit investigation of the dependence of background suppression and signal-to-noise ratio on characteristics such as: non-isotropic background with two-dimensional spatial power spectral density, background drift rate, optical blur, detector footprint, electronic sensor noise, and target phasing and velocity. Representative examples are discussed along with sample numerical results.
