METHOD OF ACQUIRING AND PROCESSING SIGNAL RECEIVED BY ARRAY OF SENSING ELEMENTS AND SYSTEM OF ACQUIRING AND PROCESSING SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a method and system for compressive array processing by using randomization to significantly reduce the sampling burden in array hardware.;SOLUTION: Signals received by an array of sensing elements are processed by first positioning the sensing elements in a uniform grid of L locations. It is selected whether each location includes a sensing element or not during a design phase. The sensing elements are selected and grouped into subsets 121. Each subset contains one or more sensing elements, and each sensing element is a member of one or more subsets. Signals in each subset are linearly combined by means 130 to produce a combined signal. Then the combined signal is sampled to form an output channel. An object can be detected by the output channel.;COPYRIGHT: (C)2014,JPO&INPIT
