Superresolution in multi-channel passive radiovision systems

Passive radiovision system is an imaging system which detects radio-thermal radiation coming from the object or scene. Widespread of the technology is delayed due to inherent features of this system - relatively poor angular resolution and slow imaging rate. The imaging rate is limited by the radiometry principle itself as the sensitivity is proportional to the integration time, which is usually around tenths of second. The problem of superresolution of passive radiovision images is considered and extension of the algorithms to the multichannel case is proposed and evaluated. The experimental data and superresolution results are presented.
