Geometric Programming for Optimizing SAR Waveform Parameters: Precursor for Cognitive SAR

Inhalt:
One of the key building blocks to realize the potential of cognitive SAR is the automatic, near real-time design and evaluation of waveform parameters (e.g. PRF, Tp) in order to adapt to varied and dynamic situations. In certain formulations, this optimization problem is non-convex, however, through geometric programming (GP), the problem can be reformulated in a convex form. In this paper, we propose an approach to find waveform parameters, optimizing for the best possible system sensitivity.
