FIELD: radiolocation. SUBSTANCE: process consists in reception of signal, in optimal or quasi-optimal filtration of it, in isolation of envelope, in comparison with threshold level. Signal is detected by excess of threshold. Before quasi-optimal filtration excessive transmission band ΔF of receiver is provided which is compared with width of main spectrum of pulse signal of duration τp, where ΔF is bigger or equal to 10/τp and signal is delayed for time τк=τp with realization of condition τк=d 1/2, where d is integral number; fc is carrier frequency. Undelayed and delayed signals are summed up with subsequent filtration in quasi-optimal filter which transmission band satisfies condition ΔFк much less than i/τp and central frequency fp= fc. In this case operations of delay and summing are repeated gamma times. EFFECT: improved authenticity of process. 3 dwg
