A fully automatic method for optimising the smoothed-pseudo Wigner-Ville distribution is presented. An alternative view on time–frequency representations (TFRs) through correlation intensity landscapes is offered, and the notion of wanted and unwanted correlations and their balance is introduced which is introduced as the measure of quality. The problem of optimising TFRs is then formulated as the...
An embedded system, based on the field programmable gate array (FPGA) technology is proposed for mitigation of a flawed-array radiation. The current solution includes a genetic algorithm (GA) that finds a new set of the array excitation parameters in case the radiation pattern of the flawed array is unacceptably degraded with respect to the originally designed pattern. A successful real-time mitigation...
The paper discusses a real-time performance of a genetic algorithm (GA) that is embedded in a Field Programmable Gate Array (FPGA) to create a system for real-time recovery of the radiation pattern of a thinned array. Major concepts of embedding an algorithm into an FPGA are discussed, along with a description of the problem and the performance of the current solution. A hybrid GA with dual-point...
