Pulse radars with UWB signals are promising as a high-resolution imaging technique that can be used for the non-destructive measurement of surface details in industrial products such as antennas and aircraft. We have already proposed a fast 3-D imaging algorithm, SEABED, that utilizes a reversible transform between the time delay and the target boundary. However, data acquisition is time-consum...

Compared to optical sensors the use of radar for earth observation has only just begun. The rst use of radar for this purpose was reported in the sixties. The most important reason to use radar instead of optical sensors is of course its capability to penetrate through clouds and its day and night imaging capabilities. However, radar interferometry might add yet another reason to use radar. Rec...

We present a physically-based clutter model for low frequency synthetic aperture radar that includes both distributed scatterers and large-amplitude discrete clutter. The model is used to generate a synthetic forest clutter scene comprised of two components, a background component and a heavy-tailed discrete component. Model parameters are based on characteristics of the scene, such as the rada...

This article deals with microwave subsurface imaging achieved by inverting the linearized scattering operator. The focus is on determination of a strategy for spatially sampling data which allows to reduce spatial measurements and at same time keep achievable performance in reconstructions. To this end, measurement points are determined order approximate point-spread function corresponding idea...

We have recently introduced a modification of the multiple signal classification method for synthetic aperture radar. This incorporates user-defined parameter, ϵ, that allows tunable quantitative high-resolution imaging. However, this requires relatively large single-to-noise ratios (SNR) to work effectively. Here, we first identify fundamental mechanism in produces images. Then introduce Kirch...

Imaging technology enhances radar environment awareness. can provide richer target information for traffic management systems than conventional detection radar. However, there is still a lack of research on millimeter-wave imaging urban surveillance. To solve the above problem, we propose an improved three-dimensional FFT algorithm architecture roadside in scenarios, enabling concurrence dynami...

Synthetic aperture radar (SAR) is an important active microwave imaging sensor [...]

In this paper, the application of vector analysis tool in the illuminated area and the Doppler frequency distribution research for the airborne pulse radar is studied. An important feature of vector analysis is that it can closely combine the geometric ideas with algebraic calculations. Through coordinate transform, the relationship between the frame of radar antenna and the ground, under aircr...

Differential radar interferometry (D-InSAR) is a powerful remote sensing technique for detection and deformation monitoring of landslides. However, as a consequence of the radar specific imaging geometry spatial distortions, such as the layover and shadowing effect, occur in the radar image, which have a negative impact on the suitability of the radar images for D-InSAR applications. Therefore ...
