Mesoscale dynamics in the mesosphere and lower thermosphere (MLT) region have been difficult to study from either ground- or satellite-based observations. For understanding of atmospheric coupling processes, important spatial scales at these altitude

Publikováno v: Atmospheric Measurement Techniques, Vol 12, Pp 2113-2127 (2019)

Typical specular meteor radars (SMRs) use one transmitting antenna and at least a five-antenna interferometric configuration on reception to study the mesosphere and lower thermosphere (MLT) region. The interferometric configuration allows the measur

Coded continuous wave meteor radar

Publikováno v: Atmospheric Measurement Techniques, Vol 9, Iss 2, Pp 829-839 (2016)

The concept of a coded continuous wave specular meteor radar (SMR) is described. The radar uses a continuously transmitted pseudorandom phase-modulated waveform, which has several advantages compared to conventional pulsed SMRs. The coding avoids ran
