1. A server for determining a location information of a vehicle emitting a radio frequency (“
- RF”
) signal, the server comprising;
a. a network connection to receive a plurality of signal measurement information from a plurality of detection devices that detect a radio signal emitted by the vehicle;
b. a processor that determines the location information using a calculation methodology based on information selected from the group consisting ofi. a received signal strength indicator of the plurality of signal measurement information at the server,ii. a time differences of arrival the plurality of signal measurement information at the server,iii. an angle of arrival of the plurality of signal measurement information at the server, andiv. times of arrival of the plurality of signal measurement information at the server, wherein the location information is transmitted to a user interface via the network connection; and
c. an RF sensor, wherein the RF sensor further comprises;
i. a first RF antenna,ii. a second RF antenna, wherein the first RF antenna detects a different frequency than the second RF antenna,iii. an RF switch to switch between the first RF antenna and the second RF antenna,iv. a preselection filter to prevent overload by electromagnetic energy in an RF spectrum at the first and second RF antennas,v. an RF tuner to down-convert the radio signal from a radio frequency signal to an intermediate frequency (“
IF”
) signal,vi. an analog digital converter to convert the IF signal to a digital format;
v. a digital signal processor to decimate the IF signal for wider RF signal spans and for identification and measurement of other signals of interest located in the RF spectrum;
viii. a global positioning system (“
UPS”
) block to generate timing signals to synchronize measurement of additional signals from additional sensors at additional locations, andix. a capture memory buffer to store a plurality of signal measurement information.
