Direction finding of a radio emission source (drone, electronic warfare, radio station, radar) using the triangulation method

✅ Minimum set: 3 analyzers, 3 directional antennas, 3 Operators.

➡️ Each Operator uses a spectrum analyzer to detect the direction of the signal source (with the greatest signal strength).
The map displays a line from the fighter’s position to the signal.
The signal source is located at the point of intersection of these lines.
👉 accuracy and range depends on many factors, see footnote below.

👉 Footnote “Important” (!)
1. For triangulation, at least 2-3 signal receivers (spectrum analyzers) are required; the more there are, the more accurate the determination of the signal location will be .
2. ONLY directional antennas are used, as they can determine direction.
3. The higher the antenna gain, the better:
– the cone of the received signal is narrower, the direction is determined more accurately;
– greater range.
4. The distance between signal receivers (operators) must be at least 400 meters, the greater the distance, the more accurate the determination of the signal location will be.

➡️ The accuracy of direction finding depends on :
– distances between direction finders (spectrum analyzers) – the greater the distance, the more accurate
– antenna gain – the higher it is, the narrower the cone of the received signal, the less the error
– distance to the signal source – the closer, the more accurate.
– number of direction finders – the more, the more accurate.

➡️ The direction finding distance (from 100 meters to 10+ km) depends on:
– power of the signal source – the more powerful the signal, the greater the distance of its detection
– antenna gain – the higher it is, the greater the distance at which the signal can be received.
