The special issue (SI) “Radar Systems for the Societal Challenges” is an updated survey of recent advances in radar systems, encompassing several application fields and related to the impact on society. In fact, radar technology is now pervasive in society and is crucial for tackling social and economic issues for the wellbeing of the population. In fact, in addition to the classical applicatio...

The effect of atmospheric propagation on radar observations is an important topic both for radar application developers and end-users of radar products, particularly of weather radar systems. An excellent review of this subject is given by Patterson (2008), and most general books about weather radars have a chapter on the topic –see for example Battan (1973), Collier (1996), Doviak and Zrnic (2...

all-weather, dayand-night imaging capability for mapping the Earth’s surface. Through interferometric synthetic aperture radar (InSAR) technique, radar imagery can be used to map Earth surface characteristics and measure land surface deformation at an unprecedented precision and spatial resolution. This article introduces the basics of radar and InSAR imaging, summarizes the revolution of InSAR...

Biological echoes are treated as contamination like ground or sea clutters by radar meteorologists as they estimate rainfall intensities or assimilate radar reflectivity into numerical forecast model. Doppler velocity measured by radar in the presence of small insects well represents air motion because small insects are considered as passive tracers. But in the presence of birds especially migr...

We describe an application that combines velocity data from a Windprofiler radar and a NEXRADII Doppler radar to compute 3D optical flow of moving severe weather. Windprofiler data improves the recovery of the velocity component in the upwards direction in the optical flow, where Windprofiler data is believed to be more accurate. We demonstrate this quantitatively using synthetic radar data and...

In Xenopus and zebrafish, BMP2, 4 and 7 have been implicated, after the onset of zygotic expression, in inducing and maintaining ventro-lateral cell fate during early development. We provide evidence here that a maternally expressed bone morphogenetic protein (BMP), Radar, may control early ventral specification in zebrafish. We show that Radar ventralizes zebrafish embryos and induces the earl...

n A new antenna and radar-cross-section measurements facility consisting of four anechoic chambers has recently been constructed at Lincoln Laboratory on Hanscom Air Force Base. One of the chambers is a large compact range facility that operates over the 400 MHz to 100 GHz band, and consists, in part, of a large temperature-controlled rectangular chamber lined with radar-absorbing material that...

This paper proposes a radar-based sensing system that estimates the coordinates for shorelines based on image-processing techniques. The proposed system provides shore estimations without appreciable loss of resolution and avoids the costs associated with bathymetries and/or satellite images. The system is comprised of a commercial radar, a GPS, and a heading sensor, which communicates to a cen...

The forward looking radar imaging task is a practical and challenging problem for adverse weather aircraft landing industry. Deconvolution method can realize the forward looking imaging but it often leads to the noise amplification in the radar image. In this paper, a forward looking radar imaging based on deconvolution method is presented for adverse weather aircraft landing. We first present ...
