讲座题目：Tractable Radar Waveform Design Under Practical Constraints
主讲人：Prof. Vishal Monga (U.S. Pennsylvania State University), Associate professor, IEEE Senior Member, Department of Electrical Engineering
报告简介：We consider the problem of optimization of radar waveforms under the crucially important constant modulus constraint -- which is hardware inspired and often combined with other constraints such as waveform similarity and spectral interference. Incorporating these constraints in an analytically tractable manner is a longstanding open challenge. This is due to the fact that the optimization problem that results from signal-to-interference-plus-noise ratio (SINR) maximization subject to these constraints is a hard non-convex problem. We will discuss a new analytical approach that involves solving a sequence of convex quadratically constrained quadratic programming (QCQP) problems, which we prove converges to a sub-optimal solution. Because an improvement in SINR results via solving each problem in the sequence, we call the method Successive QCQP Refinement (SQR). Other alternatives such as optimization directly over a complex circle manifold will be briefly discussed. Overall, we achieve a more favorable cost-quality trade-off than state of the art.
