Imaging radiometer scan simulation results

Abstract

Imaging radiometer operation is simulated by a computer program, which computes the antenna radiometric temperature as the convolution of the antenna pattern with an artificial test target brightness temperature deviation and records the data values at the sampling moments as well as the corresponding pixel coordinates. Run results proved that a well-aligned scan pattern reduces data without loss in image quality. In addition, a helicopter-borne imager was found to need at least passive attitude stabilization and the state-of-the-art sampling rate was found too slow.
