Preliminary Design Review: GMTI Narrowband for the Basic PCA Integrated Radar-Tracker Application

Abstract

This report describes ground moving target indicator (GMTI) processing to be done for the PCA (polymorphism 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 narrowband signal. For each data set, adaptive processing is used to null interference patterns and ground clutter noise. These operations incur a high computational cost. Adaptive processing requires the calculation of an adaptive filter (involving a QR decomposition and forward/backsliding) at run time for each data cube, while target parameter estimation incurs a high computation cost as more targets are detected in each data cube.
