Detection of ultrawideband chaotic radio pulses with ensemble of noncoherent receivers based on envelope detectors is investigated. Analytical solution is derived for the detection error probability as a function of signal-to-noise ratio at the detector input. The sensitivity of the radio pulse detection (by signal-to-noise ratio) is shown to increase in proportion to the number of detectors.
