Embodiments of the present invention include systems for determining locations of UWB transmitters. The system (100) includes multiple UWB receivers (104) for receiving a UWB signal (120) emitted by a UWB transmitter (106). Each receiver (104) includes: RF amplifiers (306) arranged in a cascade structure, the RF amplifiers (306) receive and amplify the UWB signal; multiple baseband blocks (308), each of the baseband blocks is coupled to the corresponding RF amplifier (306) and taps an output signal from the corresponding RF amplifier; and a processor (320) coupled to the multiple baseband blocks (308), the processor processes output signals from the multiple baseband blocks (308) to identify the UWB signal (120). The system (100) also includes a server (110) coupled to the multiple receivers (104), the server (110) receives the identified UWB signals from the multiple receivers (104) and determines the location of the UWB transmitter (106) using the identified UWB signals.
