Advantages regarding a tracking of meteors with the aid of the instruments of radio technology are related to the possibility for continuous observations without any dependence on meteorological conditions or on the time of day or night. Two methods exist for the registration of the traces of meteors, including a passive and an active method. The appropriate frequency range for both methods is the lower VHF range. For passive observations a very sensitive measurement receiver is required along with recording equipment, and a suitable antenna system. In Europe there are many television transmitters which are eminently suited for a detection of meteor traces. The active method for tracking meteors is more difficult and requires for its employment more expensive equipment than the passive method. It is based on the use of a VHF metric-wave radar. These devices operate normally also at a frequency of approximately 50 or 60 MHz. Attention is given to the theory of meteoric scattering, the various types of ionized trails, the geometry of meteor traces, results obtained in an observational station in Munich, and observations in the 144-MHz band.
