Optimal waveform design is an important component of cognitive radar, it can transmit the designed waveform to adapt environment. Many researchers focused on the next transmitted optimal waveform design according to the last target impulse response estimation. In this paper, we take advantage of the target impulse response prediction to design the next transmitted waveform for wide sense stationary-uncorrelated...
Waveforms should be synthesized efficiently according to different environment with the development of modern technology. In this paper, based on the mutual information definition of tranmitted waveform, discrete optimization model is proposed. Convex optimization method is used to design the tranmitted waveform. The simulation results demonstrate the validity of our algorithm.
It is an important problem for radar to transmit different waveforms according to different working conditions. In this paper, based on mutual information theory, a new model for optimal waveform design in single-dependent interference is proposed. Through this model, the problem of waveform design can be converted into the problem of optimization. Then we can use convex optimization method to solve...
Aiming at inherent fuzzy and uncertainty in HoQ, rough set theory with its basic principles was introduced. Rough number was proposed for the impersonal importance rating of customer requirements. The calculation of the relationship measure between customer requirements and technical characteristics, self-correlation of technical characteristics were transformed into the importance calculation of...
In cognitive radar system, how the transmitted waveform adapts in response to information regarding the radar environment is an important problem. In this paper, the waveform design for cognitive radar is viewed as an optimization problem. Then a new waveform design method for cognitive radar is proposed, which uses IPM (interior-point method) to carry out the optimization task. The simulation results...
A new method of Bayesian decision based on rough set is proposed in order to mine tacit knowledge and latent rules in support structure type selection of thrust bearing. Firstly, rough set theory is applied to reduce all factors considered in type selection for getting determinative factors. By a heuristic algorithm based on improved mutual information, the minimal attributes reduction is obtained...
