In this paper we present a low cost sub-optimum technique for the evaluation of the two-dimensional (Delay-Doppler) Cross-Correlation Function in passive radar. Its performance is characterized both in terms of computational load and expected signal-to-noise ratio (SNR) loss, compared to optimum efficient algorithms and alternative sub-optimum approaches. The comparison is conducted with reference...
In this paper we explore the maritime surveillance capabilities of the Digital Video Broadcasting Terrestrial (DVB-T) based Passive Bistatic Radar. Specifically we investigate the possibility to detect and localize vessels beyond the territorial waters since this represents a valuable characteristic for border security applications. The results are reported for the extended data acquisition campaign...
In this paper we explore the maritime surveillance capabilities of the Digital Video Broadcasting Terrestrial (DVBT) based Passive Bistatic Radar. Specifically we investigate the possibility to detect and localize vessels beyond the territorial waters since this represents a valuable characteristic for border security applications.

In this paper we present a suitable receiving and processing chain for a DVB-T based Passive Bistatic Radar (PBR) system for maritime surveillance. The proposed PBR scheme is tailored for the maritime surveillance with specific attention to the detection of targets of limited size. The work is focused on the experimental results achieved in strong collaboration between Selex ES and the University...
The integrated mobile passive AULOS® / ELT/332(V)5 system provides the detection and identification of potential air targets through the fusion of information from two sensors; it does not replace the typical active surveillance radar but it is an integrating element of the coverage of the airspace and/or of the coastal environment in areas where the traditional radar is difficult to properly work...
An innovative approach to jointly estimate and compensate the radial velocity and acceleration of non-cooperative targets in HRR (High Range Resolution) processing for a frequency stepped radar has been proposed in. The estimation is performed using different approaches mainly based on the maximization or the minimization of a proper functional (contrast, correlation-like or entropy) of the reconstructed...
Scope of the paper is to describe a technique to improve the multifunctional radar capabilitiesof tracking and classification of non-cooperative targets. The result is achieved by joining together the following two functions: (i) a tracker architecture based on Interacting Multiple Model approach and (ii) the processing of large bandwidth (either synthetic or instantaneous) signals to form Medium...
Scope of this paper is to jointly estimate and compensate the radial velocity and the radial acceleration of noncooperative targets in the HRR (high range resolution) processing for frequency stepped radar. The single velocity compensation has been studied [1]. The estimation of the acceleration throughout the proposed algorithm is derived ldquofor freerdquo from the HRR data already processed by...
A few hundred MHZ synthetic bandwidth requires the transmission of many (~100) frequency stepped pulses when a small instantaneous bandwidth (<10 MHz) is available. The actual trend in radar imaging is towards wide instantaneous bandwidth (>50 MHz) thanks to improved technology. However the need of retrofit of narrow instantaneous bandwidth to HRR (high range resolution) seems to be still cost...
