Preliminary experimental results obtained using a commercial X-band radar to detect drones are described. Trials were carried out on April 1st 2017 at the “Tor Vergata” University in Rome with the aim to compare the drone's echo to those coming from known reflectors in order to estimate the radar visibility of the drone.
The advantages of Noise Radar Technology over more conventional radars using deterministic, although sophisticated, waveforms are twofold: Low Probability of Interception/Exploitation of radar signals and mitigation of mutual interference in marine crowded environments. In this frame, the potential applications of Noise Radar Technology are many: two of them are considered in some detail, i. e. battlefield...
In the frame of the research activities of the NATO SET-184 group, and thanks to the NATO SET Panel support, experimental tests of the Noise Radar Technology have been carried out in (and near to) Warsaw, in the Autumn of 2013. The paper describes why the particular experiments were made, placing them within the context of previous noise radar trials and with those which will be carried out in summer,...
The NATO SET-225 Research Group is planning a series of live trials of Noise Radar technology to be performed in summer, 2016 at the Fraunhofer FHR Institute in Wachtberg (near Bonn). The preliminary architecture of the Demonstrator to be used in these trials is described starting from aims and requirements and arriving to define the main system functions, the parameters and the signal processor....
The better and better attention being paid to the primary resources (especially oil and raw materials) and the increasing environmental consciousness are among the main drivers of the growth of vessel traffic, also because sea shipping has a good delivery rate and affordable operating costs in comparison with other transport means. In such a frame, an effective and efficient vessel traffic requires...
The increasing environmental consciousness and the better attention being paid to the primary resources (especially oil and raw materials) is one of the main drivers of the increase in vessel traffic. Moreover, sea shipping is characterized by a good delivery rate and by affordable operating costs in comparison with other transport means, i.e. by road, rail or air. For this reasons, the continuous...
In many radar applications, including marine, automotive and MIMO, there is a need for orthogonal transmission from different radar sets to mitigate mutual interference; the same applies to the different channels in a MIMO radar. New techniques, belonging to the cyclic algorithm family, might be used to generate orthogonal signals with, in addition, low sidelobes in their autocorrelation function...
The optimal design of chirp radar waveforms has to satisfy conflicting requirements. Optimal solutions for different values of the compression ratio are considered, evaluated and compared with each other. A proposed solution has the advantage of guaranteeing low range sidelobes (less than −50 dB below the peak for compression ratios greater than 256) while maintaining the transmitter to operate in...
Noise Radar Technology (NRT) is nowadays a promising technology to achieve robustness against external interference, lack of ambiguities and high resolution. This paper is devoted to some possible applications of NRT in civil field, in particular, for the surface surveillance in airports and in sea, showing its advantages versus the more classical FM-CW or pulse compression solutions.
The well-known LPI (Low Probability of Intercept) and antispoofing capabilities of some radar waveforms as well some other desirable feature such as a low sidelobes level of their autocorrelation function can be enhanced by “tailored” pseudo-random sequences, whose phase is made up by a deterministic part plus a variable random term. With such an approach it is possible to design a virtually unlimited...
Noise Radar Technology (NRT) is nowadays a promising tool in radar systems. It is based on the transmission of waveforms composed of many noisy samples, which behave as LPI (Low Probability of Intercept) and antispoofing signals. Each noisy sequence is theoretically uncorrelated with the others. In the paper we propose a scheme to generate a “tailored” pseudo-random sequences (limited in amplitude)...
