Original methods for radar detection performance analysis are derived for a #uctuating or non-#uctuating target embedded in additive and a priori unknown noise. This kind of noise can be, for example, the sea or ground clutter encountered in surface-based radar for the detection of low grazing angle targets and/or in high-resolution radar. In these cases, the spiky clutter tends to have a stati...

Abstract: The MIMO phased array radar is a theoretical concept for multi-sensor radar planning that combines elements of traditional phased-array radar with the developing technology of multiple-input multiple output (MIMO) radar. Space-time coding (STC) has been shown to play a key role in the design of Phased Array MIMO radar where MIMO radar can achieve improved localization performance by ...

Different methods for hail detection are presented in the seminar. The presented methods use radar reflectivity measurements to determine the occurrence of hail. We compared observations made on meteorological stations, radar derived product developed by Faculty of mathematics and physics (FMF) and radar derived product VIL (Vertically integrated liquid). Comparison is performed for the period ...

We introduce the signals found in radar systems, and how the information they contain about targets can be used for fuzing. We then describe a new wavelet-based model for the random radar reflections from the ocean surface, which are a major source of noise in naval operations. Next we show ways of improving the performance of wavelet denoising when the corrupting noise is fractal. We then desc...

In this paper we investigate the dynamic range requirements of a passive radar system and show the impact of analogto-digital converter (ADC) quantization on system performance. This analysis is carried out with a view towards understanding how many ADC bits are required in each channel of the passive radar system. To give practical insight, we consider the parameters of a passive radar system ...

In this paper different CFAR detectors for detection of multiple targets for UWB radar system will be described and their outputs compared. The cell averaging CFAR (CA-CFAR) cell averaging with greatest of (CAGO-CFAR), ordered statistics CFAR (OS-CFAR), clutter map CFAR (CMCFAR) and cell averaging CFAR assumed for gamma distributed clutter will be represented. The properties of all detectors wi...

Abstract: The signal power received at an ES(Electronic warfare Support) system varies over the time due to the scan characteristics of radar, which results in the ES detection range. This paper analyzes the ES detection range for the circular scan and proposes a model to evaluate it quantitatively. Experimental results using real radars demonstrate that the proposed model is suitable for the e...

UltraWideband (UWB) systems have been utilized and commercialized since the beginning of the 1970s and have been successfully used in ground-, walland foliage-penetration, collision warning and avoidance, fluid level detection, intruder detection and vehicle radar and also for the topics of the intended research project, communication and position-location [1]. Up to now, the latter two fields ...
