Tracker-based adaptive schemes for optimal waveform selection

Abstract

Gains in processing power and advances in radar signal processing enable waveform diversity. It has been demonstrated that much can be gained with waveform diversity when previous knowledge about the environment is available, or through adaptive clutter estimation. For tracking systems, it has been also demonstrated that waveform variations in response to tracker outputs can also be beneficial. The paper focuses on the latter line of research, presenting a survey and new results pertaining to adaptation for waveform selection in tracking systems. In particular, we introduce a golden standard for adaptive methods, and show that the golden standard is satisfied for a simple adaptive law. Numerical simulations are presented to illustrate the main results in the paper.
