FIELD: physics; radio. ^ SUBSTANCE: invention relates to radio engineering and can be used in designing wireless communication, radio navigation and control systems which use broadband signals. The device for searching for broadband signals comprises a linear part (1), matched filter (2), prefilter (3), delay line (4), attenuators (51 - 5n), phase changers (61 - 6n), adder (7), detector (8), unit for comparing with the threshold (9), clock pulse generator (10), unit for controlling channel switching (11), AND component (12), comparator (13). The first input of the comparator (13) is the input for setting the threshold voltage VK, and its remaining n inputs are connected to n inputs of the adder (7). The output of the comparator (13) is connected to the second input of the AND component (12). ^ EFFECT: more stable noise immune search for broadband signals (BS) on delay, which eliminates probability of synchronisation of search devices with structural noise. ^ 4 dwg |
