DESCRIPTIVE System for detect m g the presence of a pure signal in a discreet noisecontaining signal measured at a constant mean noise level with a false detection probability below a predetermined false detection rate or level. The system makes it possible to carry out beforehand a measurement of a count NO for estimating the value of the average or mean noise level M and determine the upper limit MB of the noise and then, for detecting a signal, the system makes it possible to measure a count Ni for a time .DELTA.ti, to evaluate the information quantity I, to express this quantity in the form of a function F, which is dependent on the ratio Ml/MB1/2, Ml being equal to NiiMB and to emit a signal, whose frequency is a rising function of the quantity I. Application to the detection of radiation. (Fig. 2) B 9734.3 LB
