 note = {The radio altimeter with frequency modulated signal and frequency counting type of processing is investigated from the view point of airborne sensor at landing. The phase switching of transmitting signal is newly proposed to reduce the step error of processing. The phase switching technique is applied to the altimeter with frequencies, 4000MHz of carrier and 100MHz of band width. Some results of experiment are described with theoretical analysis., 資料番号: SA2400872000},
