synthetic pulse and antenna radar /pulsed synthetic-antenna radar
Radar A Impulsion et Antenna Synthetiques
An extraordinary concept is the French RIAS (Radar a Impulsion et Antenne Synthetique), set up by
ONERA and built by Thomson-CSF/Airsys. Fig. 2 shows a picture of the antenna system. Note the two circular arrays, sparsely populated. The array elements are mounted on the white vertical masts.
This radar operates in the HF/VHF band (50 MHz). The diameter of the outer annulus is approximately 500 m. [2-3]
