This paper is an attempt to present a short, unified discussion of the radar detection, parameter estimation, and multiple-signal resolution problems--mostly from a philosophical rather than a detailed mathematical point of view. The purpose is, hopefully, to make it possible in at least some limited sense to reason back from appropriate measures of ...

Abstract Damaging hailstorms are rare but are significant meteorological phenomena from the point of view of economic losses in central Europe. Because of the high spatial and temporal variability of hail, the proper detection of hail occurrences is almost impossible using ground station reports alone.

The detection of hail by single and multi-wavelength radar reflectivity and depolarization measurements is reviewed. There are problems of interpretation involved in the detection of hail by the Eccles-Atlas dual-wavelength (10 cm and 3 cm) method because of the possible effects of range variations of mean hail diameter and water coat thickness on hail.

CFAR detection for multistatic radar
2008 International Radar Symposium, 2008In this paper a multistatic radar system with n transmitters and one receiver is considered and several constant false alarm rate (CFAR) algorithms for detection are introduced. The decision statistics of the proposed detectors are the sum of the n largest returning signals in an array of N+n range cells.

UWB Radar for Human Being Detection
IEEE Aerospace and Electronic Systems Magazine, 2006UWB radar for detection and positioning of human beings in complex environment has been developed and manufactured. Novelty of the radar lies in its large operational bandwidth (11.7 GHz at -10 dB level) combined with high time stability. Detection of respiratory movement of a person in laboratory conditions has been demonstrated. Based on experimental

Radar detection is a particular kind of binary decision problem. Initially we shall make the simplifying assumption that the signal space also consists of only two elements and require the receiver to determine in the presence of channel disturbances whether s 1 or s 0 has been transmitted (to choose a 1 or a 0, respectively), where s 1 corresponds to ...

UAV radar imaging for target detection
Multimodal Sensing: Technologies and Applications, 2019The paper deals with subsurface imaging via radar systems mounted onboard aerial platforms. Specifically, the attention is focused on a radar prototype installed on a small unmanned aerial vehicle (S-UAV), previously proposed by few of the authors. In particular, the challenges in terms of electromagnetic modeling and flight dynamics knowledge and ...

On July 20, 1949 what are thought to be the first photographs of the radar indication of lightning strokes were obtained by the Weather Radar Research Project of the Massachusetts Institute of Technology. The method of radar lightning detection is described, and suggestions are made for research in this field.

Adaptive Radar Detection with Conic Rejection
2006 International Radar Symposium, 2006In this paper we deal with the problem of adaptive signal detection in colored Gaussian disturbance. Since the classical receivers may exhibit severe performance degradations in the presence of steering vector mismatches and sidelobe interfering signals, we try to account for the quoted drawbacks, very usual in realistic radar scenarios, at the design ...

Target detection is one of the very first operations, which has to be performed on received radar signal. The purpose of detection is normally to distinguish genuine target reflections from noise and clutter. This chapter discusses the main concepts and methods used for radar detection.
