The detection of multiple signals with no proper understanding proves to be a challenge for current UWB advanced radar collectors. It is recommended that the new smart FFT (SFFT) based collector operate at a transfer speed of 1,200 MHz. Different undersampling rates consider a bunch of big data (32,768) from the 2.56 GSPS 12-digit ADC to distinguish more signals and more precisely. The accuracy of frequency identification is achieved by 1 / fifth of the frequency target (2.56 GHz/4096) using the SFFT method. The receiver of SFFT achieves an identification rate of 90 per cent for signals as low as −19 dB SNR at a false caution rate10-7. It offers a dynamic range of 30 to 55 dB with a repeating contrast somewhere in the range of one and five containers to recognize a few signals (up to 5 signals) with varying associating speeds. On the Tesla K40c GPU, the SFFT algorithm makes some 175 μs of run memory.
