Model-Based Radar Power Calculations for Ultra-Wideband (UWB) Synthetic Aperture Radar (SAR).

摘要

In this study, we establish a relationship between the radar transmitted power, the target signature and the signal-to-noise ratio required for a specific target detection performance in a radar system. While this relationship can be easily derived from the radar equation in the case of narrowband waveforms, this technical note extends the analysis to wideband waveforms and applies it to synthetic aperture radar systems as well. The technique is demonstrated though a numerical example, where computer data modeling a three-dimensional building imaging radar system is used in evaluating the radar transmitted power for a given target detection performance.
