Radio altimeter design will be used on concorde and new french military aircraft. In conventional systems beat frequency results from comparison between frequency of transmitted and reflected signal. Cycles/sec. In beat frequency is counted and converted into aircraft height.- here, beat frequency is maintained constant by changing duration of frequency sweep. Sweep duration required for fixed beat frequency is proportional to aircraft height above ground.
