Radar scan patterns

The tables below indicate the standard possible pointing directions for the antennas for each experiment, ie. the tau2pl experiment when run on the mainland UHF system can be run with the CP1 or CP2 scan patterns.

The scan patterns, CP1 - CP7 for each site are shown below the table.

The user also can override the scan patterns with their own scan pattern if they so desire.

* UHF - Mainland UHF system; VHF - Mainland VHF system; ESR - Svalbard radar

CP Scan Patterns

The circles denotes the common volume sampled by the mainland tri-static system. The mainland system is represented by the trace on the right and the ESR system by the trace on the left. In the case where the ESR 32m dish is not pointing field aligned a blue trace indicates the 42m antenna and a red indicates the 32m antenna.

For example, the CP1 schematic shows that the UHF is able to make tri-static measurements in a single position using the tau2pl experiment(the trace on the right) while the ESR will run the steffe experiment with either the 32m of 42m dish pointing field aligned (the 42m dish is fixed in the field aligned direction).
The CP2 scan pattern shows the UHF running a tri-static scan with the tau2pl experiment in 4 different positions. The ESR is running the steffe experiment with the 42m field aligned and the 32m dish moving through 3 different positions
