Abstract
Data acquisition has been a bottleneck in Electronic Warfare (EW) applications for a long time. Data acquisition systems are expensive, power consuming and slow, and also impose limits on resolution, data transfer and processing of data. Many military applications require low power, cost effective, faster acquisition hardware. Such hardware effectively reduces the payload and data transfer requirements of military EW systems. Unfortunately, such requirements also severely stress the digital data acquisition part of the receiver system. Compressive sensing, a recent advancement in signal processing, provides a solution that appears promising for EW architectures and would relieve the stress on the analog to digital conversion (ADC) part of the receiver system. Compressive sensing may be viewed as a paradigm where sampling and compression happen simultaneously and the need for high data rate acquisitions is avoided. This report presents and overview of the compressive sensing paradigm and receivers proposed in the literature using this paradigm.
