Radar systems play a very important role in Space Situational Awareness (SSA) since they are able to provide a wealth of information on remote objects. In particular, imaging radars can characterize space objects using Inverse Synthetic Aperture Radar (ISAR) techniques. Under the right circumstances, ISAR images can provide details of a...

This paper introduces a general framework for waveform-aware optimal window design for mismatch processing. First, the linear relationship between the window function and the output of the mismatch filter, for both frequency and time windowing and a particular waveform, is modeled. Making use of such a relation, typical window constraints are...

Doppler velocity estimation in pulse-Doppler radar is done by evaluating the target returns of bursts of pulses. While this provides convenience and accuracy, it requires multiple pulses. In adaptive and cognitive radar systems, the ability to adapt on consecutive pulses, instead of bursts, brings potential performance benefits. Hence, with...

With the increased threat from advanced sensor systems using several wavelength bands and sensor fusion, the requirements on camouflage increase. Consequently, in order to reduce the risk of EU soldiers being detected, identified and engaged, adaptive camouflage prototypes have been developed, implemented and demonstrated. Several active and...

While the concentrations of trace gases in Earth’s atmosphere were roughly constant for thousands of years, human activities such as the burning of fossil fuels have caused significant changes ever since the industrial revolution. The remote sensing of trace gases has proved to be a useful technique for mapping and monitoring on the global scale...

Radar and sonar information processing is a promising application area of quantum computing in the near future. Many use cases in this area can are computational heavy and might benefit greatly from a quantum approach. In this paper, an overview of use cases in this application area is given and scored on quantum readiness, added value and...

We present a simple and useful figure of merit (FoM) with which to evaluate the performance of simultaneous-multi-beam (SMB) transmit (TX) antenna arrays. The FoM builds upon the power-aperture product and effective isotropic radiated power for single-beam arrays and extends it to SMB arrays. The FoM is the product of radiated power, antenna...

Automotive engineers are repeatedly faced with the issue of choosing radars with the best angular resolution while having reduced processing times. In this paper, a novel extrapolation method is presented to estimate the amplitudes and phases for virtual antenna elements at the receiver periphery. This method has shown to resolve two targets...

This paper investigates the benefits of multichannel processing for inverse synthetic aperture radar (ISAR) imaging. There are potential advantages of multichannel processing in radar systems, for example, improved motion estimation, clutter suppression, extraction of supporting information, such as sea wave direction and speed, and ship wake...

It is well known that noise-like waveforms have the inherent property of suppressing ambiguities due to their nonrepetitive nature, as opposed to the more classical linear frequency modulated (LFM) pulsed waveforms. This aperiodicity also improves the robustness against jammers, making these waveforms harder to detect and classify by an enemy....

Recent advances in digital beam forming for phased arrays in combination with digital signal processing should enable the development of multibeam radar in a bistatic configuration. In the bistatic setting, the pulse travelling outward from the transmitter should be followed or “chased” by the receiver. During transmission, depending on the...

In this article a novel waveform based on agile (or irregular) pulse intervals is presented as a potential approach to simultaneously resolve both range and Doppler ambiguities using a single burst in radar measurements containing very far away and/or very fast targets. The paper shows that, the combination of irregularly spaced transmitted...

The use of drones grows rapidly, recreational and commercial use, as well as malicious use. Following the trend of increasing use, there is an increasing need for radar systems to detect, track and characterize drones. Drone characterization, i.e., extracting information about the payload and intent of a drone, is crucial for the effective...

Camera systems are widely used for surveillance in the security and defense domains. The main advantages of camera systems are their high resolution, their ease of use, and the fact that optical imagery is easy to interpret for human operators. However, particularly when considering application in the defense domain, cameras have some...

The ALFA project aims at timely detection, tracking, classification, and intent assessment of LSS targets. The system relies on a heterogeneous sensor suite, including radar. The objective of the radar component is sector surveillance including target classification. Since the revisit time needs to be short, classification must be done with very...

The article presents the design of a Ka-band synthetic aperture radar (SAR) instrument based on innovative phased-array antennas, with steering capability in azimuth and elevation. To limit the complexity and costs associated with conventional large active arrays with regular layouts, a sparse array concept is presented. The proposed approach...
