Abstract
Способ локализации зон шумоизлучения по длине движущегося транспортного средства, включающий прием сигналов в двух произвольных точках его волнового поля, полосовую фильтрацию принятых сигналов, задержку сигнала, снимаемого с выхода приемника, ближнего к траектории движения транспортного средства, на величину, равную максимальной относительной задержке принимаемых сигналов, определение корреляционной функции между полученными сигналами и ее свертку с функцией, имеющей спектр обратный спектру корреляционной функции для независимого точечного источника шумоизлучения, отличающийся тем, что после фильтрации принятых сигналов на измененной частоте и задержки отфильтрованные сигналы и корреляционная функция умножаются по частоте в число раз, равное отношению начальной и измененной частот фильтрации.A method for localizing noise emission zones along the length of a moving vehicle, including receiving signals at two arbitrary points of its wave field, band-pass filtering of received signals, delaying the signal received from the output of the receiver closest to the vehicle’s trajectory by an amount equal to the maximum relative delay of the received signals , determination of the correlation function between the received signals and its convolution with a function having a spectrum inverse to the spectrum of the correlation function for independent o a point source of noise, characterized in that after filtering the received signals at a changed frequency and delay, the filtered signals and the correlation function are multiplied in frequency by the number of times equal to the ratio of the initial and changed filtering frequencies.
