Περιγραφή: В статье рассматривается принцип формирования частичнокогерентных сигналов путём ретрансляции зондирующих импульсов радиолокаторов с синтезированной апертурой с частичным разрушением их когерентности, которые обеспечивают формирование на радиолокационных изображениях тестовых шумоподобных областей в интересах осуществления радиометрической калибровки радиолокационных средств дистанционного зондирования Земли. Обоснованы требования к точности временной синхронизации работы ретранслятора с зондирующими импульсами радиолокатора с синтезированной апертурой. The article discusses the principle of forming partially coherent signals by relaying the probing pulses of radars with a synthesized aperture with partial destruction of their coherence, which provide the formation of test noise-like areas on radar images in the interests of radiometric calibration of radar means of remote sensing of the Earth. The requirements for the accuracy of the time synchronization of the repeater operation with the probing pulses of the synthetic aperture radar are substantiated.
