Knowledge of altitude and ionization curves of faint meteors is of great importance for the calculation of meteor detectability during radar observations (Greenhow and Hall, 1960; Lebedinec, 1963). Greenhow (1963), using the simplest physical theory of meteors (Herlofson, 1948) for altitude calculations, arrived at a conclusion that radar observations of very faint meteors were impossible for practically any radar power. The simplest physical theory of meteors is used for calculations of radar-meteor detectability by almost all the authors. Lebedinec (1963) has shown that this theory is inapplicable in the case of faint meteors since one should take into account energy losses caused by thermal radiation from the meteoroid surface.
