Development of Surveillance and Tracking Radar

A high-resolution surveillance and tracking radar has been recently developed and tested at the Institute of Radio Astronomy. The radar is a monopulse, all-weather radar with mechanical beam steering. It works in a pulse mode, and a coherent FFT-based signal processing is utilized. The radar is equipped with a clutter suppression system and with a Kalman filtering scheme for trajectory calculation and extrapolation. The radar is suitable for long-range surveillance with a small volume-scanning time and for tracking of highly dynamic, low-sized targets. This paper describes the setup of this radar, its main components, and the signal processing technique used
