This report describes the performance prediction models for the passive narrowband (PNB) and passive broadband (PBB) automated detection (AD) modes of ARCI and APB 1. Ideal lower bounds on detection performance are formally derived for known target bearings and frequencies. These results are used later in the report to bound the range of detection degradation for estimated target tracks. The mo...
The effect of passive iron converters on the detection efficiency of neutrons in a plastic scintillator was investigated at energies of 20–140 MeV. An enhanced detection efficiency for neutron energies above 70 MeV was found using iron converters of 2–3 cm thickness. The experimental results are compared to a simulation. 2002 Elsevier Science B.V. All rights reserved.
This paper concerns the detection, parameter and height estimation of PN signals, with a passive radar receiver network applied in wireless communication systems, in multipath interference. The investigation is obtained by Monte Carlo simulation. The achieved results can be applied for target detection in multistatic radars using existing communication networks.
This article addresses the problem of clutter cancelation for slowly moving target detection and localization in multichannel passive radar onboard mobile platforms. A post-Doppler space-time adaptive processing (STAP) approach is exploited case an angle-dependent imbalance affecting receiving channels. While suppression capability ensured by adaptivity filtering, different solutions are compar...
