Abstract

The invention discloses a transmitting-receiving isolation forwarding interference method and a forwarding interference device based on an analog delay line. The forwarding interference method comprises the following specific steps: receiving and amplifying a radiation source signal to obtain a first signal; performing interval on-off processing on the first signal to obtain a second signal with a preset interval on-off duration; performing delay processing on the second signal through an analog delay line to obtain an interference signal; and amplifying and transmitting the interference signal. According to the invention, fast time-division isolation forwarding is realized through the analog delay line, the system design difficulty and the forwarding interference cost are effectively reduced, and the bandwidth processing range is widened.

Description

technical field [0001] The present application relates to the technical field of electronic countermeasures, and in particular, to a method and a forwarding interference device for transmitting and receiving isolation and forwarding interference based on an analog delay line. Background technique [0002] The forwarding jamming technology introduces a jamming signal that is highly similar to the target echo at the radar receiver end by receiving, processing the radar signal and amplifying the transmission, so as to obtain the radar signal processing gain and the jamming effect of generating false targets. In modern jammer systems widely used. Because the transceivers work on the same frequency, the isolation problem of transceivers has always been a difficulty in the design of such jammer systems. Time division transceiver isolation is widely used in communication and radar systems working on the same frequency. The time division transceiver isolation method applied to the...
