Radio Direction Finding (DF) is the art of determining the location of an emitter and is used in search and rescue, coastal surveillance, law enforcement and defence. There are different techniques using power and phase but the output for a single sensor is normally a Line of Bearing (LoB) which points towards the emitter.

We have proven we can improve upon this with modelling and can reduce the search area significantly, even when the radio power is unknown.

The modelling came from SOOTHSAYER 1.10 which was installed upon a Raspberry Pi 5. Only one (CPU) API call was necessary per test cycle to generate a grey scale Path Loss map in decibels (dB) from which subsequent received power heat maps in decibel milliwatts (dBm) could be rapidly derived using a simple link budget.
