DETECTOR OF SIGNAL BURST Russian patent published in 2007 - IPC G01S7/28 G01S7/292 

FIELD: radio engineering, applicable, in particular, in the systems of automatic measurement of target angular coordinates (elevation angle, azimuth).

SUBSTANCE: the signal burst detector has a reversible counter (1), upper threshold comparator (2), lower threshold comparator (3), integrator (19), first (21) and second (22) switching circuits, delay line for the period of repetition (23). Input (25) serves as the detector input, input (26) - as the threshold level input, input (27) - as the nullification pulse input, input (28) - as the maximum code limitation input, output (29) - as the signal burst detector output.

EFFECT: enhanced precision of measurement of the time of beginning and end of the signal burst in an adaptive mixture with noise, characterized by fading of the reflected echo signals in the minima of the target reverse dispersion diagram and, respectively, precision of measurement of target angular coordinates and rejection of the noise bursts exceeding the threshold level of the detector.
