Abstract

PURPOSE:To obtain a device superior in conformity with a comparatively simple constitution by most strongly outputting the received waves into the connection terminal of a part corresponding to the direction of its arrival when the radio waves are received on a lens antenna. CONSTITUTION:An ECM (Electronic Counter Measures) device is connected to a lens antenna 10 and a plurality of the connection terminals 12-1 - 12-n of the antenna 10 respectively to process the received waves from the connection terminals to make them jamming waves and a plurality of the repeater jammer circuits 14-1 - 14-n for transmitting to the connection terminals are provided. And when the radio waves are received in the antenna 10, the received waves are most strongly output into the connection terminals of the part corresponding to the direction of its arrival. In addition, on the contrary, when transmitted waves are supplied to the connection terminals, the radio waves are transmitted to the direction of the arrival of the received waves. Accordingly if the circuits 14-1 - 14-n are connected to each connection terminal 12-1 - 12-n of the antenna 10, the repeater jammer circuit corresponding to the arrival direction of the radio waves are operated to immediately return the jamming waves to its arrival direction.

However, with the conventional ECM device described above, it is necessary to allow sufficient time for azimuth analysis, analyze the radar waves after reception, set a modulation method for effective jamming, and mechanically or electronically scan the radar waves. The antenna that sends out the jamming waves had to be redirected to emit the jamming waves, which caused problems in quick response and also made the equipment larger and more complex.

On the other hand, in terms of operation, the burn-through range (distance where the power of the reflected wave from the detection target and the jamming wave from the ECM are the same).Beyond this distance, the power of the jamming wave becomes larger, so effective jamming cannot be achieved. (within this distance, the power of the reflected wave becomes larger, so jamming is no longer possible.) has changed, and as this distance is getting further away, the requirement for the magnitude of the jamming power has changed. , the demand for quick response is becoming stronger.

The signal is delayed by a predetermined amount at , and the phase is shifted by a phase controller 150 . The amount of phase shift in the phase controller 150 is changed each time a pulse is received, and a phase shift similar to a Doppler shift is applied to create an interference wave. The switch 152 is closed during the output period of the interference wave, and the interference wave is returned to the beam port from which the radar wave was received via the transmission amplifier 154 and the transmission/reception switch 142.
