Waveform Codesign for Radar–Communication Spectral Coexistence via Dynamic Programming
IEEE Transactions on Aerospace and Electronic Systems(2022)
Abstract
In this article, we develop a new waveform codesign approach for radar–communications spectral coexistence using a decision-theoretic framework called
partially observable Markov decision process
(POMDP). The POMDP framework’s natural look-ahead feature allows us to trade off short-term for long-term performance, which is necessary in waveform codesign problems with competing objectives and dynamic user needs. As POMDPs are computationally intractable, we extend two approximation methods called
nominal belief-state optimization
and
random-sampling multipath hypothesis propagation
to make the codesign approaches tractable.
