This paper presents a new development of a 24 GHz radar frontend with a Rotman Lens as a beamforming network. The main objective of the project is the accurate detection and localization of multiple targets at the same distance from the radar system. Interferometric systems determine the direction for a target with the phase difference through at least two receiving antennas. If multiple targets are...
In the past period, great efforts have been made to develop methods for the people detection based on monitoring their respiratory motion using ultrawideband (UWB) radar. The basic principle of the respiratory motion detection consists in the identification of sensor signal components possessing a significant power in the frequency band 0.1–0.7 Hz (frequency band of human respiratory rate) corresponding...
This article s focused on radar technology and radio surveillance systems produced in Czech republic as a part of Czechoslovakia until 1990s. During this era there were produced thousands of radars for military and civil purpose for air traffic control, ship navigation, meteo radars, fire control and air defense radars used worldwide. The special domain in electronic location and surveillance systems...
