The use of commercial off-the-shelf (COTS) technologies in military environment is attractive, but in tactical communications, one of the biggest challenges is the jamming/interference tolerance of the deployed systems. Interference tolerance is important also in public authority and in some special civilian wireless network set-ups. We present an experimental measurement-based study on jamming tolerance...
IEEE 802.11 based WLAN systems have gained interest to be used in the military and public authority environments, where the radio conditions can be harsh due to intentional jamming. The radio environment can be difficult also in commercial and civilian deployments since the unlicensed frequency bands are crowded. To study these problems, we built a test bed with a controlled signal path to measure...
In this paper we introduce a batch frequency domain scheme for wideband jammer nulling with multichannel synthetic aperture radar (SAR). This is compared to the wideband extension of the SLC approach. We analyze the nulling performance for several image acquisition modes and interference scenarios and show that both algorithms are adequate in terms of cancellation level. The frequency domain approach...
