What is "tira"

is a fictional character in the Soul series of video games. She was created by Namco's Project Soul division. Tira was originally introduced in Soulcalibur III and has returned in Soulcalibur IV and Soulcalibur V. A mentally unstable young woman, Tira is a former member of an assassination guild, the Bird of Passage, who left the group due to her state, eventually becoming a loyal servant of the cursed sword, Soul Edge, and its wielder, Nightmare. While originally only having a case of split personality, the influence of Soul Edge and its counterpart, Soul Calibur, breaks Tira's mind even further that she currently possesses two different personalities: jolly and gloomy.

The character is positively received by the public, often noted for her unique style of clothing and sexual appeal, although her fighting style has received mixed reception, with some citating it difficult to control. Tira's likeness has been also used on various merchandise related to the series.

The Tracking & Imaging Radar (TIRA) system serves as the central experimental facility for the development and investigation of radar techniques for the detection and reconnaissance of objects in space, and to a certain degree also of air targets. TIRA has a 34-metre parabolic dish antenna is a monopulse radar operating at 1.333 GHz or 22.5 cm ( L band) and 16.7 GHz or 1.8 cm ( Ku band) wavelengths. The L-band is usually used for tracking debris with a 0.45° beam width, at 1 MW peak power. The system is capable of determining orbits from direction angles, range and Doppler shift for single targets. The detection size threshold is about 2 cm at 1000 km range. The radar conducts regular ‘beam park’ experiments, where the radar beam is pointed in a fixed direction on the celestial sphere for 24 hours, scanning 360° in a narrow strip a complete Earth rotation. The tracking sensitive can be enhanced when the TIRA system is used as a transmitter, part of a bistatic radar system. In conjunction with the Effelsberg Radio Telescope, functioning as a receiver, the combined system has a detection size threshold of 1 cm. The Ku-band is used for imaging in Inverse Synthetic Aperture Radar (ISAR) mode, with 13 kW peak power, the radar is capable of producing images with range resolutions better than 7 cm. The dish can be turned full 360° in azimuth with speed of 24° per second and 90° in elevation. The radar is protected by a radome with 47 meters diameter - one of the largest in the world.

Due to its capabilities, the system is used as a radar tracking system for space debris and other in-orbit object in the ESA's Space Situational Awareness Programme (SSA).

TIRA is located at the FGAN site, in Wachtberg near Bonn, Germany. It is run by the Fraunhofer-FHR - the Fraunhofer-Institut für Hochfrequenzphysik und Radartechnik (High Frequency Physics and Radar Techniques).
