Abstract
1. Способ обнаружения радиолокационных сигналов, основанный на согласованной фильтрации с усилением сигнала и фильтрации его огибающей, на сравнении отфильтрованного колебания с порогом, который устанавливают в зависимости от уровня помех в интервале времени, заключающем в себя интервал вероятного приема сигнала, после чего обрабатывают колебание аналогично основной обработке, измеряют уровень помех и по полученному уровню устанавливают порог обнаружения, отличающийся тем, что, с целью подавления нестационарных широкополосных помех одновременно с основной обработкой, в принимаемом сигнале удаляют рабочий сигнал.2. Устройство обнаружения радиолокационных сигналов, содержащее последовательно соединенные согласованный фильтр, выход которого является входом устройства, детектор огибающей, вычитающее устройство, пороговое устройство и дополнительный детектор огибающей, причем выход дополнительного детектора огибающей соединен со вторым входом вычитающего устройства, отличающееся тем, что дополнительно имеет режекторный фильтр, вход которого соединен с входом устройства, а выход с входом дополнительного детектора огибающей.1. A method for detecting radar signals based on consistent filtering with amplification of the signal and filtering its envelope, by comparing the filtered wave with a threshold, which is set depending on the level of interference in a time interval that includes the interval of probable signal reception, after which the oscillation is processed similarly main processing, measure the level of interference and set the detection threshold according to the received level, characterized in that, in order to suppress non-stationary broadband interference simultaneously with the main processing, the working signal is removed in the received signal. 2. A radar signal detection device comprising a matched filter connected in series, the output of which is an input to the device, an envelope detector, a subtractor, a threshold device and an additional envelope detector, the output of an additional envelope detector connected to a second input of the subtractor, characterized in that it additionally has a notch filter whose input is connected to the input of the device, and the output to the input of an additional envelope detector.
