Abstract: Изобретение относится к радиолокации и может быть использовано для обнаружения импульсных радиосигналов в условиях узкополосных активных помех. Технический результат - повышение помехоустойчивости обнаружения импульсных радиосигналов в условиях узкополосных помех и белого шума без разрушения выходного сигнала обнаружителя при неизменных энергетических и частотно-временных ресурсах радиоканала. Согласно способу неразрушающего обнаружения импульсных радиосигналов осуществляют оценку частот, мощностей и полос частот узкополосных помех и согласованную с входным сигналом фильтрацию. По выходному сигналу согласованного фильтра выбирают моменты времени взятия информационного и опорного отсчетов, в которых измеряют соответствующие значения сигнально-помеховых реализаций, и вычисляют значение коэффициента корреляции результирующей помехи между информационным и опорным отсчетами. На противоположном фронте выходного сигнала согласованного фильтра выбирают моменты времени взятия дополнительных информационного и опорного отсчетов, в которых измеряют соответствующие значения сигнально-помеховых реализаций, и вычисляют значение коэффициента корреляции узкополосной помехи между дополнительными информационным и опорным отсчетами. По измеренным сигнально-помеховым реализациям в информационных и опорных отсчетах и вычисленных значениях коэффициентов корреляции результирующей помехи между соответствующими информационными и опорными отсчетами вычисляют результирующую величину, которую сравнивают с заданным пороговым значением, и по выбранному критерию принимают решение о наличии или отсутствии сигнала на входе обнаружителя. 2 ил.
