Abstract
A simulator for simulating radar or sonar signals returned to an observation point from a three-dimensional object of non-uniform reflectivity. An imaginary three-dimensional object is defined spatially in the form of a series of three-dimensional regularly shaped elements. Each element has allocated to it a predetermined level of uniform reflectivity.The position of boundaries of the element along an imaginary radial line extending from the observation point are calculated and the reflectivity allocated to points on the line on each side of each of the boundary positions is calculated. A sequence of signals is then generated which is representative of the allocated reflectivities occurring along the length of the line.
