DETECTION OF PULSED SIGNALS IN NOISE. AN EXPERIMENTAL STUDY BASED ON THE MARCUM THEORY,
Abstract
In applications involving the detection of pulsed signals in random noise, the theoretical work of Marcum has proven useful. The calculation of detection probability as a function of signal-to-noise ratio and number of pulses integrated has been accomplished by Marcum and the data presented for a wide range of parameter variation. An experimental investigation was undertaken to verify the results of Marcum and to relate the assumptions and approximations contained in the theory to a practical embodiment. The instrumentation consisted of a simulated pulsed-radar receiver, scaled down in frequency for convenience, in which i-f pulses generated by gating the output of a CW oscillator were combined with random noise, bandpass filtered and square-law detected. The desired number of detected pulses were then added and applied to a threshold detector by means of which the probability of exceeding a given threshold could be determined. (Author)
