cassbeam package information
A program for Cassegrain antenna modelling
Cassbeam is a Cassegrain antenna ray tracer. A Cassegrain antenna is a double reflector system which works on the principle of cassegrain optical telescope. A high gain cassegrain reflector antenna in Ku-band has been successfully developed for command transmit application for the missile programme. It can also be used for monopulse radar, satellite communication. Based on an input text file, it computes several properties of the antenna including gain, zenith system temperature, and the beam, in full polarization. All calculations are done in the transmit sense and use reciprocity to relate to the equivalent receiving system. Additionally, cassbeam allows deformations, or pathologies of the optics to be modelled. Currently this is limited to rotations and translations of the feed and secondary. In the future, large scale deviations in the primary (such as a misplaced panel) will likely be supported.
More information about apt-get remove
Advanced Package Tool, or APT, is a free software user interface that works with core libraries to handle the installation and removal of software on Debian, Ubuntu and other Linux distributions. APT simplifies the process of managing software on Unix-like computer systems by automating the retrieval, configuration and installation of software packages, either from precompiled files or by compiling source code.
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using the APT library.
apt-get remove is identical to install except that packages are removed instead of installed. Note that removing a package leaves its configuration files on the system. If a plus sign is appended to the package name (with no intervening space), the identified package will be installed instead of removed.
