    摘要: The invention allows the detection and processing in a radio signal received by a receiver, of any signal of “pulsed” type present in radio signals applied to the input of a radiofrequency receiver, the receiver having an analogue/digital converter for performing the coding into digital on N bits of P successive samples of the analogue signal applied to the input of the receiver and a computer for processing the said digital signals, characterized in that on the basis of a histogram of the rate of occupancy of the digitized samples, graded in ranges Fx of amplitude-increasing sample levels, is determined, from among the ranges Fx, a range Fn onwards of which the total number of digitized samples Nnor contained in the ranges Fn and those below Fn is greater than or equal to a normality threshold Nn, Nn being a number predetermined as a function of the sensitivity of the detection of pulsed signals that one wishes to achieve.

    摘要: Method for the elimination in a receiver of an incident signal resulting from multipaths, characterized in that an array of 2n auxiliary sensors (2, 3, Ca to Cf), with n≧3, is constructed around an antenna main sensor (1), these auxiliary sensors all being equidistant from the main sensor and regularly spaced apart, and, by successively taking the pairs of auxiliary sensors symmetric with respect to the main sensor to determine the direction of arrival of the signal resulting from the multipaths, the weighted combination of the signals arising from the n sensors is performed, the direction of the transmitter being known (ejφi).

    摘要: Apparatus and methods degarble a received broadband radio signal using spatial filtering. The apparatus and methods use various garbled versions of the signal delivered by parallel processing chains assumed to have the same transfer function. Automatic equalization (4d), at the level of the outputs of the processing chains (2a to 2g), is performed before the spatial filtering (3). The automatic equalization reduces disparities, innate or originate from drifts over time, between processing chains (2a to 2g), and uses a local test signal generator (5).
