Radio Direction Finding (RDF) refers to any technique used to determine the directional bearing toward an RF transmitter.

The simplest method is to use an antenna that only receives signals from the direction in which it is pointed, then manually sweeping through 360 degrees to identify the bearing angle that receives the strongest signal. You could then do this from multiple locations and make note of where your bearings intersect. Unfortunately, this "simple" method requires a tuned directional antenna and a manual, error-prone process.

Multipath

Multipath is the arrival of a transmitted signal at a receive antenna from multiple paths due to reflections. The reflections can occur from the ground, trees, buildings, people, or whatever is around. As an example, see Figure 1. The dominant signal is often the Line of Sight (LOS) signal, which is the direct path from the receiver to the transmitter. The other arriving signals (due to reflections) are known as multipath. In some situations (particularly in urban environments), there is no line of sight signal, and all received rays are from multipath. Multipath causes significant variation in received signal - sometimes the multipath reinforces the received signal, but often it subtracts from it (a phenomenon known as fading). See also diversity reception.

Radio fingerprinting - Radio Frequency Fingerprinting

A radio transmitter fingerprinting system
This thesis is concerned with an approach to record, process, and classify radiotransmitter transients. A radio transmitter transient is emitted by the transmitterwhen the transmitter's push-to-talk button is depressed.

What is Radio Frequency Fingerprinting
Radio frequency fingerprinting is a process that identifies the device or signaler from which a radio transmission originated by looking at the properties of its transmission, including specific radio frequencies. Each signal originator has its own specific "fingerprint" based on the location and configuration of its

Radio fingerprinting is a process that identifies a cellular phone or any other radio transmitter by the "fingerprint" that characterizes its signal transmission and is hard to imitate. An electronic fingerprint makes it possible to identify a wireless device by its radio transmission characteristics. Radio fingerprinting is commonly used by cellular operators to prevent cloning of cell phones — a cloned device will have the same numeric equipment identity but a different radio fingerprint.
