<I>Abstract: </I><br><br>
We consider the issues of landing a space landing module (LM) on the surface of a planet using the example of the Moon. Graphs of the time dependence of the values of the height and vertical velocity of the LM at its final stage, starting from a height of 5000 m, are presented. It is proposed to use a radar with continuous radiation of 3-4 harmonics, a phase meter for echo signal delay, and a Doppler frequency shift meter as an on-board sensor for the indicated LM motion parameters. A block diagram of a radar and a range (altitude) meter is proposed. Calculations of methodological errors in measuring the height and vertical speed of the PM at various heights were carried out. The maximum measurement errors (within ±3σ) do not exceed the specified values.
