Abstract: The present description concerns a method of processing by a radio transmitter/receiver (12) of a radio signal (SR) comprising a telecommunications signal disturbed by pulses of a radar signal, the method comprising the steps of: estimating the instantaneous power of the pulses, estimating the ratio of the average power of the telecommunications signal to the instantaneous power of the radar pulses, and modifying the radio signal at the locations of the radar pulses when said ratio is smaller than a threshold.

Abstract: A passive radar comprises a reception antenna for a signal transmitted by a non-cooperative transmitter, the received signal comprising a static contribution related to propagation of the signal transmitted through a multi-path propagation channel and a dynamic contribution related to propagation of echoes of the transmitted signal from a moving target. The passive radar also comprises a reception chain that includes an analogue-digital converter capable of outputting a digitised signal, a moving target detection unit, a digitised signal processing unit configured to determine an estimation of the static contribution during a calibration phase of the passive radar, a transmission chain that can output an analogue signal representative of the estimation of the static contribution, and a directional coupler configured to output the signal received during the calibration phase of the passive radar to the reception chain.

Abstract: A transceiver for In-Band Full-Duplex communication is provided. The transceiver includes a duplexer and a bidirectional frequency transposition module, the frequency transposition module being suitable for transposing a signal to be transmitted, with a predetermined frequency shift, ?F, in order to obtain a transmit signal, and for transposing the receive signal, with the same frequency shift, in order to obtain the received signal, with the frequency band of the signal to be transmitted and the frequency band of the received signal thus being separated by a frequency shift which is double the predetermined frequency shift.
