Dual software and hardware refocusing of satellite reflectors

The present paper concerns the possibility of hardware and software recovery of the reflector antenna by means of measuring the hardware system function (HSF), i.e. its response to artificial point sources. This HSF measurement detects the “disease” of the reflector system, i.e. measure deviations from the ideal parabolic shape. Usually this deviation occurs in the outer space, for example, due to thermal deformation.
