The paper describes the design and experimental performance assessment of the RF front-end of an airborne P-band ice sounding radar. The ice sounder design features newly developed components at a centre frequency of 435 MHz, such as, antenna 20% bandwidth at RL ≪ 13 dB, compact high power in-phase and out-of-phase power dividers with a relative bandwidth of 20% and more than 75W CW power handling, high power SPDT PIN switch with 90W CW power handling and a 70W CW High efficiency LDMOS power amplifier with ≫60% power-added efficiency.
The system comprises also a digital signal generator, a digital front-end and a control unit. The system was functionally tested in March 2008 and had a first successful proof-of-concept campaign in Greenland in May 2008.
