We tackled a problem of research into temperature field that makes it possible to determine effectiveness of the fire-retardant coating applied onto metallic wall. When stating the problem, we took into account a nonstandard temperature regime and co

The robust estimation of far-field radiation pattern from the near-field measurement data, which are distorted by additive noise and random impulses, is suggested. The proposed technique is based on the two-stage algorithm. The first stage is to dete

Approach to robust estimation of radiation sources in an array of electric dipoles when measurement data are distorted by additive noise as well as by random impulses is suggested. It is based on a non-linear optimization technique where objective fu
