FIELD: radiolocation, possible use for determining angular coordinates of active noise jammers and for estimating frequency distribution of power of active noise interference in working frequency range of direction-finder. ^ SUBSTANCE: one-channel amplitude multi-frequency direction finder of active noise interference contains antenna, receiving device, analog-digital converter, detector, azimuth packet memory block, azimuth packet restoration block, integrator, signal amplitude memory block, comparison block and computing block for determining azimuth position of active noise jammer, and also threshold level generation block, all interconnected in a certain way. ^ EFFECT: increased precision when measuring angular coordinates of active noise jammers due to adjustment to frequency with maximal interference/noise ratio. |
