MODE OF COHERENT ACCUMULATION OF RADIO IMPULSES Russian patent published in 2007 - IPC G01S7/292 

FIELD: the invention refers to radio technique and may be used in coherent storage devices of impulse signals formed by incoherent impulse sequence.

SUBSTANCE: radio impulses are limited along a spectrum, optimally filtered, detected, compared with the first threshold of detection, a time strobe designed for time selection of in time delayed impulses is formed, radio impulses are delayed on 0,6 of the duration of a radio impulse with forming the first quadrature component and on 0,6 of the duration of a radio impulse with forming the first quadrature component and on 0, of the duration of the radio-impulse plus T_n/4 with forming the second quadrature component and on time iDT where DT=1/M f₀, f₀ - a carrier frequency, i= 1,2 M(M≥10), with forming M channels of delayed signals. These M delayed signals are selected according to the time with the aid of the formed strobe, quantized and digitized, quadrature components after selection according to the time are quantized, with getting samples, squared, summed up, the received signal is compared with the second threshold, then the number of samples that exceeded the second threshold and also isolated and two in a row passes are counted and an impulse of selection in accordance with its duration is formed, digitized amplitudes of samples are also stored in accordance with the duration of the impulse and compared, in the process of comparison the digitized sample that has the maximum level in the moment of coming in of the impulse of selection is formed in accordance with its duration and the number of the corresponding channel is defined and the number of the channel is used for choosing the corresponding memory register for coherent accumulation of this signal.

EFFECT: increases noise immunity from noise and impulse interference.
