Method for formation of radiometric images and an antenna for implementation of the method

摘要

A method of radiometric image generation is provided using a series of isochronous revolutions of a multi-beam antenna with a dispersion characteristic. The antenna is combined with a multi-channel receiver with frequency channel separation to form an imaging unit. The method comprising cyclically executing the following phases: two separate calibration phase; using first and second standards; external radiation reception phase; data processing phase and data transformation phase.
