IsoLOG Directional Finding

The IsoLOG Directional Finding block shows you the direction of any selected RF signal(s) in real-time and high accuracy on a map:

The IsoLOG Directional Finding block offers all you need to setup a perfect DF (Directional Finding) application in 3D. It supports our ultra fast sector switching of down to 1µs to catch even ultra short signals. For the usage of this block you need our unique, patented IsoLOG 3D DF antenna array which can detect all RF signals within a broad frequency range in 3D.

 

The IsoLOG Directional Finding block then offers a real-time visualization of the signal(s) of interest: A powerful fully featured online (open streetmap) or offline map support incl. topographic display is the basic. Within this map you can see the GPS Position of the IsoLOG 3D DF antenna and a highly accurate beam and antenna sector graph showing where the signal is coming from. Even the declination/height of the signal(s) are shown.

An additional directional heat map helps you to better locate moving or very short signals e.g. short pulses or bursts down to a view µs.

Below that map you get a spectrum and histogram view of the RF spectrum where you can select the signal of interest.

 

Varios adjustments are possible to optimize your setup:

A typical DF setup in action might look like this (tracking a drone video signal):

Even ultra short bursts e.g. coming from a Bluetooth device can be tracked down with the help of the additional IQ Direction Power Spectrum block:
