DISD mathematical model for the soft Lunar landing projects
Abstract:
Doppler measurer of velocity and range (DISD) provides detection and radiolocation capture of the signal reflected form the underlying surface. DISD is used in the soft Lunar landing projects. Mathematical models of range and velocity measurement and of normal angles determination are considered in the paper. The functioning of the DISD device is described. The algorithm converting measurements into range values is presented.
