How accurate is TDOA geolocation?

TDOA (Time Difference Of Arrival), also known as multilateration, is a well-established technique for the geolocation of RF emitters. Using three or more receivers, TDOA algorithms locate a signal source from the different arrival times at the receivers. We trust that existing users of CRFS’s TDOA geolocation know, from their own experience, that it is very accurate and effective for most signal types. New [...]

Minimum detectable signal and maximum detection range

The minimum detectable signal for a given range, or maximum range for a given signal power, is not as simple a question as one might think. Here we will see how this answer is dependent on a number of mission-dependent factors. Since minimum detectable signal and maximum range are closely related problems, we will focus here on the example of minimum detectable signal. Interfering [...]

Droning on about RF?

The growing threat from commercial drones has generated a wave of activity from vendors claiming that RF detection and geolocation offer a complete solution. In this article, we will explore whether RF is really the whole answer. The problem Drone-related incidents in recent years include near misses with passenger aircraft, smuggling contraband goods into prisons the discovery of a drone containing radioactive caesium on [...]

Mathematical Manipulations: 1000 × Power(1 − 80%) of the performance for 20% of the cost?

CRFS prides itself on its high-performance RFeye® superhet receivers, so when we heard claims of low-cost spectrum analyzers/Software Defined Radio (SDR) receivers with 80% of the functionality of a high-performance receiver for 20% of the price, our curiosity was piqued. We set out to crunch the numbers and see if this 80%/20% claim has any truth to it. Noise figure, or Displayed Average Noise Level (DANL), [...]
