INTERROGATION SIGNAL DECODING DEVICE Russian patent published in 2015 - IPC G01S13/78 

FIELD: radio engineering, communication.

SUBSTANCE: interrogation signal decoding device containing ADC, a decoder of interrogation signals, which includes a shift register unit, the fist AND element, the second AND element and a group of AND elements, a signal amplitude comparison assembly, which differs by the fact that in order to improve the probability of decoding of an interrogation signal under conditions of a complicated interference situation, there additionally introduced to it is a counter, the first, the second, the third, the fourth and the fifth RAM, an interrogation mode decoding assembly and a preliminary signal processing assembly with the corresponding links. The preliminary signal processing assembly includes the first, the second, the third, the fourth, the fifth, the sixth and the seventh comparators, the first, the second, the third and the fourth registers, the first constant unit, the second constant, the first and the second subtractors, the first and the second adders, the first and the second triggers, the third, the fourth, the fifth, the sixth, the seventh, the eighth and the ninth synchronous triggers, the first, the second, the third, the fourth, the fifth and the sixth AND elements, the first, the second, the third, the fourth and the fifth OR elements, the first, the second, the third and the fourth pulse shapers, a counter and a decoder. The interrogation mode decoding assembly includes a constant assembly, a subtractor assembly, a pulse shaper, the first, the second, the third, the fourth, the fifth and the sixth registers, a counter, the first, the second, the third and the fourth synchronous triggers, a delay element, the first, the second, the third, the fourth, the fifth, the sixth and the seventh AND elements, the first, the second and the third OR elements.

EFFECT: improving the probability of decoding of an interrogation signal under conditions of a complicated interference situation.
