RADIO FUSE WITH LINEAR FREQUENCY MODULATION SIGNAL Russian patent published in 2019 - IPC F42C13/04 

FIELD: radar ranging.

SUBSTANCE: invention relates to the field of radar equipment and can be used in devices with continuous frequency-modulated probing signals for fixing a predetermined range to an object when approaching it. Radio fuse with linear frequency modulation of the signal comprises series-connected first sawtooth voltage generator, autodin-based transceiver module, phase detector, signal analyzer and actuator. Additionally, a synchronizer, a second sawtooth voltage generator, a pseudorandom sequence generator, first and second switches, wherein the output of the synchronizer is connected to the inputs of the first and second sawtooth voltage generators, the first input of the phase detector and the input of the pseudorandom sequence generator. Outputs of the first and second sawtooth voltage generators and the pseudorandom sequence generator are respectively connected to the first, second and third inputs of the first switch, the output of which is connected to the input of the transceiver module, which output is connected to the first input of the signal analyzer and the input of the phase detector, the output of which is connected to the first input of the second switch, and the output of the pseudorandom sequence generator is also connected to the second input of the second switch. First and second outputs of the second switch are connected to the second and third inputs of the signal analyzer, respectively. Device can be used in non-contact detonators, in range sensors, altitude sensors etc.

EFFECT: invention increases noise immunity of the device from the action of relay interference stations.
