Ground electromagnetic smog estimation from airborne measurements: an effective approach

A new approach to find the electromagnetic field distribution on the ground from airplane surveys is proposed. The method exploits a temporal and spatial incoherent electromagnetic model of the radiation and an on board array antenna made of few elements. By solving a regularized ill-posed inverse problem, the technique allows the estimation of the on the ground intensity scene, taking explicitly into account the noise and the measurement errors due to the aircraft deviation from the nominal flight path and attitude of flight.
