Abstract :
A mobile instrument for the measurement of ice and frost thickness on lakes and bogs has been developed. It is an FM-CW radar with separate transmitting and receiving antennas operating in the frequency range 1...1.8 GHz. The display of the radar consists of an audio spectrum analyzer with a led matrix of 12 × 32 leds (32 channels indicating different thicknesses). Experimental results show that the ice thickness can be measured with a sufficient accuracy as well as the frost thickness when the bog is relatively wet.
