Sample clock offset must be estimated in order to correctly demodulate an OFDM signal. Estimates are also required in passive radar processing, to produce a reference signal, which is properly matched to the transmission. A recently proposed clock of

Passive radar signal processing is hindered by the need to sample a reference signal from the chosen illuminator, which is subject to sensor noise and interference from clutter returns. The reference signal may be demodulated and reconstructed to rem

Second-order difference array (SODA) interferometry provides unambiguous high-accuracy direction of arrival (DOA) estimation of RF signals. A low-resolution unambiguous DOA estimate is formed by interferometry with a receiver pair having short separa

Algorithms based on the Wiener filter provide effective clutter cancellation in passive radar. However such algorithms are computationally intensive. Recently some Fourier-domain techniques have emerged for efficient clutter cancellation when the ill

Delay-Doppler filtering enables the isolation of radar returns from a designated region of the ambiguity plane. Such returns can be cancelled from the surveillance signal, lowering the ambiguity floor and reducing demands on dynamic range. Modern pas

Passive sensing involves the exploitation of ambient radio-frequency transmissions to infer the presence and properties of reflectors in the vicinity. With multiple receivers the directions of arrival (DOA) may be estimated. Interferometry is a simpl

In passive bistatic radar, the detection of moving targets is enhanced by cancellation of low-Doppler returns from the surveillance signal. Strong returns from small moving objects can also impact upon detection statistics. Methods of point clutter r

Recent studies investigated square-complementary waveforms for sidelobe suppression in radar. Targets were assumed to have a constant radar cross section (RCS). However, complex targets exhibit a RCS that varies wildly with frequency. This study revi
We were most interested to read the letter1 from Martyn Walling about the insertion technique for the etonogestrel implant. We too have adopted his technique of injecting local anaesthetic only at the site of needle puncture and not along the length
