Atmospheric microwave refractivity and refraction [PDF]

open access: yes
The atmospheric refractivity can be expressed as a function of temperature, pressure, water vapor content, and operating frequency. Based on twenty-year meteorological data, statistics of the atmospheric refractivity were obtained.

MarsLux: HI-Resolution Illumination Maps Generator for Mars [PDF]

open access: yes, 2019
Illumination simulation codes for the Moon's surface have been thoroughly developed during the last years. Despite works done for the Moon, no studies have investigated the relation between sunlight illumination and the Martian surface applying those ...

Airborne antenna coverage requirements for the TCV B-737 aircraft [PDF]

open access: yes
The airborne antenna line of sight look angle requirement for operation with a Microwave Landing System (MLS) was studied. The required azimuth and elevation line of sight look angles from an antenna located on an aircraft to three ground based antenna ...

Estimation of wind-induced pressures on a low-rise building using quasi-steady theory

open access: yesFrontiers in Built Environment, 2016
A quasi-steady (QS) model that includes both the instantaneous wind azimuth and elevation angle is applied and extended to relate the instantaneous wind speeds and roof pressures for a typical low-rise building.

Amplitude scintillations on earth-space propagation paths at 2 and 30 GHz [PDF]

open access: yes
Amplitude scintillation measurements were made simultaneously at 2.075 and 30 GHz on earth-space propagation paths over elevation angles in the range 0.4 to 44 deg.

Investigation on the Phantom Image Elevation Effect [PDF]

open access: yes, 2015
Listening tests have been carried out in order to evaluate the phantom image elevation effect depending on horizontal stereophonic base angle. Seven ecologically valid sound sources as well as four noise sources were tested. Subjects judged the perceived

Bearing-Based Leader-Follower Formation Tracking Control Using Elevation Angle

open access: yesIEEE Access
This paper studies the elevation angle-based formation tracking control of multi-agent systems. Unlike bearing-based formation control, which uses bearing vectors, formation control using elevation angles eliminates the need for a global coordinate frame.

New optical and radio frequency angular tropospheric refraction models for deep space applications [PDF]

open access: yes
The development of angular tropospheric refraction models for optical and radio frequency usage is presented. The models are compact analytic functions, finite over the entire domain of elevation angle, and accurate over large ranges of pressure ...
