The opportunity to use the geostationary satellite radio signals at high elevation angles for determining parameters of hydrometeors (rain, snow, hail, clouds) is discussed. The attenuation and scattering of radio waves allow one to determine the average moisture and drop concentration in stratocumulus clouds, the reflection of radio waves from cumulonimbus clouds provides information on the intensity...
The principle of developing the pseudo-coherent radar [transmitter based upon the small-size cold-cathode magnetron (1kg)], which allows locating nearly objects and eliminating the influence of internal noise and of reflections from the sea surface, is presented. It allows locating small-size high-speed light vessels in a ship's wake.
The function circuit and performance characteristics of dual band radioelectronic facilities (DBRF) “Burevisnyk-3”, which is a new-generation complex integrated radio electronics system operating in the X-band and Ka-band wavelength with a unitary control system, are described. The above radar system is intended for technical surveillance and monitoring of open water area situation. It is located...
An unconventional principle of a constructing coherent pulse high duty-factor radar is described. It is shown that the function circuit of the coherent pulse radars that were built around the structural concept already described does not involve the phasing of a heterodyne reference signal.
In order to protect territorial waters from illicit fishing, waterage and other violations the over-the-horizon detection of surface objects at the 3-cm wavelengths is considered. Application of a bistatic radar with the use of an active lightship, set beyond the bounds of the horizon, was proposed.
