An airborne system comprising four SARs that operate in the C - ((lambda) approximately equals 4 cm), L - ((lambda) approximately equals 23 cm), P - ((lambda) approximately equals 68 cm) and VHF - ((lambda) approximately equals 250 cm) - bands is presented. A general description of each SAR is given together with its basic performance characteristics. Design peculiarities of transmit- receive channels, antenna units, radar data recorders and digital data processing algorithms are discussed. Terrain radar images obtained with the use of SARs operating at different wavebands with various polarizations are presented.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
