Summary:
A measurement technique for calibrating the HPS(Hongik Polarimetric Sactterometer) for L-, C-, X-band frequencies is presented in this paper. Especially, to overcome the integration problem with a large L-band sensor part, we propose a new compact OMT (Orthogonal Mode Transducer) for L-band. The performances of the integrated HPS system for multi-bands on single platform was evaluated and calibrated by the STCT (Single Target Calibration Technique) and the 2DTST (2D Target Scanning Technique). The evaluation of the calibration accuracy in the field experiment can secure the precise calibration accuracy within 0.5 dB for magnitude correction and less than 4? for phase correction in each bands.
