Monopulse synthetic aperture radar

Monopulse synthetic aperture radar for fast, high-resolution imaging of ground and/or airborne objects comprising illuminating transmitting means, receiving means covering entire space sector by set of non-scanning antenna beams and processing means for processing reflected signals

• wherein:
• transmitting and receiving means arranged as monopulse transceiver modules wherein each monopulse transceiver module covering as minimum one said space sector;
• each monopulse transceiver module consists monopulse processor and as minimum one transmitter connected to as minimum one transmitting antenna covering said space sector and set of non-scanning receiving antennas with overlap antenna patterns in quadrature or multi-axis directions and covering same space sector, wherein each of receiving antenna coupled to separate receiver chain;
• each receiver chain coupled to monopulse processor for simultaneous multi-axis processing of all signals in receiving chains in reference to amplitudes, phase and frequency components shift of signals in overlap receiving antennas;
• outputs of monopulse processor and receiver chains connected to image generator by digital interface;
• image generator consists quadrature or multi-axis multi-channel processor for simultaneous processing of all signals in receiving chains including amplitude, phase and frequency components shift of signals in receiving antennas and generating image including information received from monopulse processor;
• all transmitters, receiver chains and processing means connected with synchronization means;
• transceiver modules, image generator and radar output chain connected by microwave and/or fiber optic digital interface.
