摘要： Method and apparatus for leakage signal cancellation in a simultaneous transmit and receive RF system includes: generating a digital transmit signal for transmission from the system; receiving a receive signal produced by reflection of the transmit signal from an object or generated by a second RF system; adaptively filtering the transmit signal by an adaptive finite input response (FIR) filter; calculating filter coefficients for the adaptive FIR filter in real-time at a different sampling rate; adaptively inputting the calculated filter coefficients to the adaptive FIR filter to generate a cancellation signal in real-time; and applying the cancellation signal to the receive signal to cancel leakage in the receive signal to generate an optimum receive signal.

摘要： A system for transmitting and receiving electromagnetic waves simultaneously. A portion of a signal to be transmitted through a transmitting antenna element is diverted from a transmit signal path, processed by an adjustable filter, and coupled into receive signal path. The adjustable filter is adjusted to approximate the channel that the leakage signals go through to get from the transmitter to the receiver so that the signal coupled into the receiving path through the filter partially cancels the parasitic leakage from the transmit signal path to the receive signal path.

摘要： An RF module including transmitting, receiving, and processing elements, capable of operating in a standalone mode or as part of an array of similar or identical modules. The RF module includes a radiator (205), transmit-receive circuitry (165), a digital receiver-exciter (160), a processor (100), and a data interface (150). The processor is configured to exchange in-phase and quadrature data with other processors in an array, so that, when configured as an array, digital transmit beam forming and receive beam forming are possible.
