“…The advantage over active radar systems lies in reduced costs, the ability to operate covertly and hence being insusceptible against anti‐radiation missiles or electronic countermeasures, and improved detection of stealth targets because of bistatic configurations. Meanwhile, all kinds of available signals, such as analogue as well as digital audio or video broadcast [1–3], cellular phone networks [4], satellite signals [5–7] or wireless local areas networks [8, 9] have been investigated for passive radar purposes. The recent interest in using digital waveforms as illuminators of opportunity is partly because of the fact that they are exactly specified in technical norms which allows us to reconstruct a multipath‐free reference signal.…”

This study focuses on passive coherent location using global system for mobile communications base stations transmitting mainly dummy bursts in idle mode. The authors present adaptive delay line canceller techniques to suppress the zero-Doppler direct path and its clutter almost down to the receiver noise level. The proposed approaches offer the following two advantages compared with the other clutter cancellation techniques: they are fail-safe with respect to the errors in the reference signal extraction simply because they do not require any knowledge of the reference signal and they even work in severely non-stationary clutter conditions. The effectiveness of the approaches is demonstrated by means of measurements recorded with an experimental passive bistatic radar system
