VELEZ, JUAN C.; LISHAK, MIJAIL Y.  e  ANTONOV-ANTIPOV, YURY N.. FALSE ALARM AND DETECTION PROBABILITIES CALCULATION OF A DIGITAL UNIFIED DETECTOR. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.162, pp.271-280. ISSN 0012-7353.

The central objective of the present work is to find analytical expressions for the detection and false alarm probabilities computation in a nonlinear digital detector, used as the main detection device of a receiver that processes communication and navigation signals with low signal to noise ratios and high Doppler shifts. In order to accomplish this task, the energy spectrum of the squared complex envelope of the incoming process and the resulting p.d.f out of the Fourier processor are calculated. These results allow to find the curves of detection probabilities of the signal, for a given false alarm probability, and compare them with experimentally curves, found by means of simulation.

Palavras-chave : detection; detection probability; false alarm probability.
