    RF Interference Cancellation Systems

    Cobham Antenna Systems miniaturised INterference CANcellation (mINCAN) system eliminates mutual interference when multiple radio systems are integrated into tactical land, marine and airborne platforms.

     

    The Problem

     

    The complexity of modern communications and counter IED systems combines with the

    compactness of the platforms they are installed on to create major co-site interference problems.  This is made much worse when frequency agile radios and broadband monitoring receivers are involved.  The result is that many receivers will receive levels of interference from co-sited transmitters that cause unacceptable noise levels and some receivers may be driven into blocking.

     

    The Solution

     

    The principle of Cobham Antenna Systems Interference Cancellation system is deceptively simple: the removal of interference by injecting an accurately scaled anti-phase version of the interfering RF signal. This can be achieved for multiple transmitters and receivers from HF through to microwave frequencies.

     

    The principle is similar to acoustic noise cancellation systems in car phones and hearing aids. mINCAN can handle very high levels of received interference and at the high hopping speeds of modern frequency agile transmitters.  A sample of the signal from the co-sited transmitter is taken using a directional coupler in the transmit antenna feed. It is then scaled in phase and amplitude before being algebraically added to the receive path to cancel out the co-sited interference.

     

    Modular and Adaptable 

     

    Multiple interfering transmitters can be cancelled by allocating a cancelling module for each interfering transmitter.

     

    mINCAN is fully adaptive, it does not need a direct interface to the transmitter or receiver.  By interfacing only with the antenna feed cables it ensures that installation on new or legacy platforms is a straight forward process. The benefit of mINCAN's high speed cancellation is effective before the interfering signal reaches its full amplitude.  This ensures that receiver blocking does not occur.
