This paper presents a general scheme for automatic signal detection in scanning surveillance systems. It considers the problem of deciding whether an alert situation exists, based on the data measured in the cell under analysis in di!erent consecutive scanning time instants. The proposed scheme includes a linear predictor and a subspace model for the signal to be detected, in an attempt to maxi...

In the recent years, the radar technology, once used predominantly in the military, has started to emerge in numerous civilian applications. One of the areas that this technology appeared is the automotive industry. Nowadays, we can find various radars in modern cars that are used to assist a driver to ensure a safe drive and increase the quality of the driving experience. The future of the aut...

Recent advances in the development of semiconductors allow the realization of low cost hardware architecture for implementing Barker and Nested binary codes suitable for radar applications. Due to the fast development in Digital Signal Processors (DSP) they are used in radar signal processing. Radar signal processing is defined as exploitation of the received signal represented in digital form ...

In previous work, electromagnetic matchedeld processing was proposed for estimating aircraft altitude with over-the-horizon radar using a single radar dwell. Although this approach exploits the altitude dependence of unresolved multipath returns in complex delay-Doppler space, its performance su ers in situations where the coherent integration time (CIT) of the radar is short. To overcome this ...

Coherent and non-coherent radar detection of moving targets is analyzed and expressions relating the post-video-detection moving target signal-tonoise ratio to the pre-video-detection moving target signal-to-noise and clutter-to-noise ratios are obtained for non-coherent detection. The effect of processing this resulting real (non-coherent) signal with an FFT processor is then analyzed and comp...

This paper describes a real-time implementation of adaptive range oversampling processing on the National Weather Radar Testbed phased-array radar. It is demonstrated that, compared to conventional matched-filter processing, range oversampling can be used to reduce scan update times by a factor of 2 while producing meteorological data with similar quality. Adaptive range oversampling uses momen...

In this paper, a software tool developed in Matlab for stepped-frequency GPR (Ground Penetration Radar) is presented. It is intended for data simulation, image formation and basic GPR signal and image processing. The designed software can be useful for the researchers to help them analyze the performances of the different algorithms for data acquisition, signal processing and image processing. ...

The work presented in this paper is aimed at the implementation of a real-time multiple-input multiple-output (MIMO) imaging radar used for area surveillance. In this radar, the equivalent virtual array method and time-division technique are applied to make 16 virtual elements synthesized from the MIMO antenna array. The chirp signal generater is based on a combination of direct digital synthes...

Performance assessment (PA) provides an important tool for radar system evaluation. In addition to allowing comparison of different signal processing algorithms and sequences on a near real-time or synoptic basis, it can also allow determination of the performance envelope of the radar system by defining the surveillance area over which the system is routinely expected to detect targets. The us...
