Institute of Space and Astronautical Science JAXA develops the radio altimeter and velocity meter (landing radar) that is one of mandatory navigation sensor for a planetary lander. The landing radar can measure its relative altitude and speed from planetary surface by C band (4.3 [GHz]) pulse. The BBM (Bread Board Model) with the function which can measure speed and altitude simultaneously was manufactured and the field experiment has been done by using helicopter that carried the BBM radar. From the result of the field experiment, the BBM radar realized the design performance and attained 5 [percent] of the required accuracy from the lander system. It was also able to evaluate the geographical feature dependability of measurement accuracy by comparing a natural surface with an ideal surface at the Airport. This paper introduces the BBM and the algorism of altimeter and describes the result of field experiment.
