Analytic study on feasibility of using microwave radiometry as technique for navigation data sensing in U S Army aircraft; various means of sensing passively aircraft velocity, altitude, and velocity-altitude ratio were considered; while there appears to be no practical method for direct measurement of either velocity or altitude separately, it does appear possible to measure velocity-altitude ratio by comparing radiometric signals received from terrain along aircraft ground track; when combined with radar altimeter, such sensor could yield navigation data compatibile with Army aircraft requirements.
