Q-Learning-Based Adaptive Waveform Selection in Cognitive Radar
Cognitive radar is a new framework of radar system proposed by Simon Haykin recently. Adaptive waveform selection is an important problem of intelligent transmitter in cognitive radar. In this paper, the problem of adaptive waveform selection is modeled as stochastic dynamic programming model. Then Q-learning is used to solve it. Q-learning can solve the problems that we do not know the explici...

Cognitive radar is a new framework of radar system proposed by Simon Haykin recently. Adaptive waveform selection is an important problem of intelligent transmitter in cognitive radar. In this paper, the problem of adaptive waveform selection is modeled as stochastic dynamic programming model. Then backward dynamic programming, temporal difference learning and Q-learning are used to solve this ...
متن کاملAdaptive Waveform Design for Cognitive Radar in Multiple Targets Situation
In this paper, the problem of cognitive radar (CR) waveform optimization design for target detection and estimation in multiple extended targets situations is investigated. This problem is analyzed in signal-dependent interference, as well as additive channel noise for extended targets with unknown target impulse response (TIR). To address this problem, an improved algorithm is employed for tar...
متن کاملAdaptive Distributed MIMO Radar Waveform Optimization Based on Mutual Information
In recent years, the research on adaptive radar waveform design has received great impetus. Some of the noteworthy works in this area include [1]—[5], where the radar transmission parameters are continuously modified in order to improve the target parameter estimation in a time-varying radar environment. Another related development is the proposal of cognitive radar, which represents an innovat...
متن کاملResearch on Model and Algorithm of Waveform Selection in Cognitive Radar
Cognitve radar can be aware of its environment, utilize intelligent signal processing, provide feedback from the receiver to the transmitter for adaptive illumination and preserve the information contents of radar returns. In this paper, based on the analysis of the parameters of radar mesurements, range-Doppler resolution cell is built up, then stochastic dynamic programming model of waveform ...
