algorithm
An amplitude method is suggested for estimating target elevation from theamplitude ratio of pulses measured in adjacent beams of the partial antennapattern. The method is suitable for application in conjunction with elevationangle measurements based on the azimuthal width of echo pulse burst reflectedfrom the target. A functional diagram of thespecialized processor to implement the suggested method has been developed.

The problem solution is presented on determining the magnetic flux induced by a plane waveinside of a ferrite cylinder used as a basic element of a high‐sensitivity magnetic antenna. The model problem represents the diffraction of a plane electromagnetic wave by an infinite circular magnetodielectric cylinder of an arbitrary radius. Field distributions outside and inside of thecylinder are constructed. A resonance behavior of the magnetic flux is indicated.

plasma-beam instability
The multi-harmonic cubic-nonlinear theory of a plasma-beam superheterodyne free electron laser with H-ubitron pumping is developed. The multi-harmonic interaction of waves, which plays an essential role, is considered. The analysis of the saturation levels is performed. It is found that prospects of practical use of the considered systems for generation of especially powerful electromagnetic signals of the mm-wave band could be rather promising.
