Enhanced Meteor Detection Radar – EMDR
The Enhanced Meteor Detection Radar System (EMDR) is designed specifically for wind profiling in the Mesosphere Lower Thermosphere (MLT) region (70-110 km) by tracking the drift of ionisation trails left by meteoroids as they fall through the atmosphere.
The system is designed to support both attended and unattended operation. It can be operated and monitored remotely and data can be automatically analysed and posted to an web site. It may be readily expanded to accommodate higher power operation and to include Boundary Layer Spaced Antenna operation.
The EMDR has many applications, which include:
- Wind and temperature profiling
- Meteor astronomy
- Rocket launch support
- Meteor tracking and recording
- Atmospheric research
- Data acquisition and analysis
