SLRAR

The Side-Looking Real Aperature Radar (SLRAR) on Cosmos-1500 was the first spaceborne SLRAR. The instrument was constructed and developed at the Institute of Radiophysics and Electonic (IRE) of the Ukranian Academy of Sciences to provide 2-dimensional images of ice and oceanographic scenes. The SLRAR operated at a frequency of 9.5 GHz in vertical (V) polarization providing 0.8 x 2.5 km resolution and a swath width of 425 km. SLRAR data were processed on-board and transmitted directly to ships and automated data receiving stations. The data were used to make high resolution radar maps of ice cover in the Arctic and Antarctic. The data were also used to derive wind speed and direction at the ocean surface. All-weather radar imagery were provided to the user community in real-time by means of a 137.4 MHz Automatic Picture Transmission (APT) channel. Imagery from the SLRAR on-board Cosmos-1500 was used to rescue about 50 Soviet ships trapped in heavy ice in the Arctic during the polar winter of 1983. In 1986, real-time data was used to rescue the inhabitants of a research station in Antarctica. The SLRAR instrument was a precursor to other radars used on the oceanographic series of satellites (Okean-1. -2, and -3). Similar instruments were used on the Cosmos-1602 and Cosmos-1766 spacecraft.
