Preliminary Design Review: GMTI Processing for the PCA Integrated Radar-Tracker Application
Abstract
This report describes ground moving target indicator (GMTI) processing to be done for the PCA (polymorphous computing architecture) integrated radar-tracker application. GMTI processing of the raw radar data is done to extract targets; target reports are passed on to the tracker part of the integrated radar-tracker application. The GMTI processing described in this report is used to minimize the effects of interference patterns and ground clutter and to recognize and extract targets on the ground. The radar is presumed to be using a wideband signal for improved resolution. This signal is decomposed via subband filtering into many narrowband signals for easier processing. Each of these subbanded data sets must then be processed as a distinct radar data cube. For each data set, adaptive processing is used to null interference patterns and ground clutter noise. These operations incur a high computational cost. Subband filtering requires many parallel modulators and filters, while adaptive processing requires the calculation of an adaptive filter (involving a QR decomposition and forward/backsolving) at run time for each subband data cube.
