Doppler radars for the spacecrafts landing on Moon and planets of solar system
Space Research Institute of Russian Academy of Sciences, Moscow
Methodic aspects of altitude and velocity measurements of the spacecrafts meant for the soft landing on Moon and planets are considered. The errors of doppler meters of velocity, inclined range and altitude using FM and multi-frequency signals as well as errors of the phase radar altimeter with the wide antenna directional pattern are evaluated.
Keywords: phase radar, radar altimeter, radiovertical, frequency scale, landing, accuracy, noise, variance, bias, dynamic error
