How to set path azimuth when defining positions of transceivers

Conventions for azimuth angle definitions

• For the path azimuths in the Wt-Vr and It-Wr links, the reference point is a transmitter and the angle is from the positive direction of Ox axis to the path towards a corresponding receiver in a link.

• For the path azimuth used in describing relative Vr-It positioning, the reference point is at Vr and the angle is between the positive direction of Ox axis and the path towards the It.

These principles of defining azimuth angles are illustrated in the following picture.

Example of entering azimuth angles

By means of example, the geometric positioning of victim and interfering systems in the above figure could be programmed within the SEAMCAT interference scenario in the following way:

• It-Vr path: relative location mode: none, path azimuth - constant at 45 deg, appropriate distance parameters;
• It-Wr path: path azimuth: 0/90 deg;
• Wt-Vr path: path azimuth: 0/90 deg;
• Vr antenna pointing: either 0 deg or e.g. uniform azimuth: -45/+45 deg;
• It antenna pointing: either 0 deg or e.g. uniform azimuth: -45/+45 deg.
