Horizontal Scan

Horizontal Scan plots the signal strength versus the angle of incidence on a polar diagram.

The measured signals are normalized to the maximum value linearly during the

measurement (1 = 100 % signal strength). The display allows you to more easily see the

difference between the received signal and the reflections that occur. The SignalShark

automatically calculates the bearing of the signal source based on the horizontally measured

values.
The calculation of the main angle of incidence is performed where possible using a quadratic

regression of the measured values obtained. Otherwise, the azimuth angle of the maximum

level is assumed to be the direction of transmission and a message to this effect is displayed.

General operating steps

Following step may help you to successfully run a horizontal scan:
