Inverse Synthetic Aperture Radar (ISAR) is used to produce high resolution imagery of non-cooperative targets by retrieving the relative motion parameters of a target with respect to a reference. This concept of estimating motion parameters is applied for obtaining cross-range resolution in ISAR imaging in which one component is produced by the relative motion between the radar and the target a...

The stratigraphy of an alpine snowpack is very important for avalanche danger assessment, as well as interpretation of remote sensing measurements for hydrological purposes. Since spatial variability is often widespread, due mainly to wind, micro-climatic and topographic effects, extrapolating point measurements can be difficult. Tools which can quickly characterize snowpack stratigraphy, such ...

By mounting the transmitter and receiver of Frequency Modulated Continuous Wave (FMCW) Synthetic Aperture Radar (SAR) system on separate platforms, bistatic FMCW SAR offers more considerable capabilities, reliability and flexibility while maintaining the small size, low cost and agile reaction. The bistatic FMCW SAR raw signal simulator is highly required to quantitatively support the design of...

A multiple-target tracking problem for a frequency-modulated continuous-wave (FMCW) radar network is formulated and an integrated track management system is presented to solve the tracking problem in the presence of clutter. The FMCW radar network obtains beat frequency measurements with multiple collocated radars, each transmitting a sequence of chirps. The beat frequency measurements are asso...

Especially for the long distance Frequency Modulated Continuous Wave(FMCW) radar applications, the non linear frequency sweep due to the Voltage Controlled Oscillators (VCO) results in range resolution degradation. Open loop control solutions like Voltage Pre-Distortion method are not adequate for the applications like FMCW Radar Altimeter because of the noisy and non-stationary structure of th...

The presentation discusses the requirements on the characteristics of antenna and RFsubsystem of a FMCW Imaging Radar with respect to the dynamic range and presents the design of an advanced demonstrator. The discussion is based on experience with the HiVision-Radar system /1/ which observes the ground from an elevated position (e.g. airborne platform, see also /2/) and employs a frequency scan...

There are a number of potential applications for low cost short range phased array radar sensors: ship bumpers, large vehicle sensors and level crossing obstacle detection for example. Phased arrays have the benefit of reduced size and the elimination of moving parts compared with more traditional rotating antenna systems. Another potential benefit is that the image update rate can be orders of...

High-frequency (HF) surface wave radars provide a unique capability to detect targets far beyond the conventional microwave radar coverage. This capability also could contribute to the development and improvement of Tsunami Early Warning Systems. This paper presents the system design and introduces the key signal processing methodologies that enable the HF radar to provide early warning of the ...

This article deals with the development of a dual channel S-Band frequency-modulated continuous wave (FMCW) system for a through-the-wall imaging (TWRI) system. Most existing TWRI systems using FMCW were developed for synthetic aperture radar (SAR) which has many drawbacks such as the need for several antenna elements and movement of the system. Our implemented TWRI system comprises a transmitt...

This paper presents an algorithm for 60GHz FMCW radar detection system providing precise distance and velocity measurements. A digital simulation environment based on the radar hardware setup is built to evaluate and demonstrate the applicability and performance of the detection system under laboratory conditions. The system first incorporates a normal FFT for general frequency estimation, base...
