MRL-1

The MRL-1 (Cyrillic: МРЛ-1, abbreviation of Метеорологический РадиоЛокатор) was a non-coherent weather radar operating in Ka- and X-Bands. It was the first dual-band weather radar.

It was developed around 1967 and was used as a precipitation radar in the former Soviet Union. However, it was quickly realized that such high frequencies were ineffective for a precipitation radar. This led to the development of the MRL-2, which used only the X-band part. Even in this band, the RF energy is attenuated too much by precipitation, so that only the leading edge of the bad weather areas could be seen. This then led to the development of the MRL-5 with even lower transmit frequencies.
