Radar detectors with signature recognition

Signature technology

— support by the device of signature recognition of signals of a radar. Its principle is that the device does not simply react to the presence of radiation in a particular range (as with conventional recognition), but analyzes this radiation and determines whether it corresponds to the characteristic features (signature) of the radar. Thus, the number of false alarms is significantly reduced: the device gives a signal only when it detects the characteristic radiation of the radar. In addition, this technology even allows you to recognize specific radar models and inform the driver about it. Among the disadvantages of signature recognition, in addition to the increased cost of radars, one can note a reduced (on average by 10–20%) response speed. In addition, the signature memory is limited, it usually contains data only from the radars of a certain region. So when buying a device with this function, it is worth considering for which region the radar detector was originally intended.
