Popis: | In the complex background of information warfare, we often encounter multiple air defense radars or multi-band radars and carry out effective jamming against them simultaneously. Due to that radar always works at different frequencies, we need to generate jamming signals with sufficient bandwidth, covering all frequencies of radar and aiming at each band at the same time for jamming, which is called multi-point targeting jamming. In this paper, using two coherent optical frequency combs through the Vernier caliper effect with frequency “dislocation” is proposed, and produce multiple stable central frequencies through beat frequency. This scheme can realize widely tunable frequency bands. And this paper implemented maximum tunable range of 1.1–23.4 GHz with 100 MHz bandwidth. |
