Abstract:

An existing system using NRLs Senrad radar is being used to demonstrate the utility of wideband waveforms in radar surveillance. This system processes data using a stretch technique to yield high resolution range profiles of the target. To provide some of the benefits of greater bandwidth without implementing the wideband waveforms, it was suggested to add bandwidth extrapolation processing. The addition of this processing necessitated changes to the existing system for real-time processing. The changes included modifying the Volume Surveillance system hardware, constructing an interface between the existing system and the Volume Surveillance processor and modifying the stretch and bandwidth extrapolation software for a new processor. The changes were implemented and the modified hardware operated correctly. The software modifications were tested successfully with recorded and real-time data. The processing times met the time specifications necessary for real-time operation. Bandwidth, Extrapolation Stretch,
