FT-RF
SYNTHETIC-APERTURE RADAR
( SAR )
The SAR has 15,360 antennas and operates in the X-band, transmitting a peak RF power of 4kW (~250MW EIRP) at a duty cycle of 5%~10%, and the average DC power consumption is less than 4000W. It consists of 5 synchronized phased array antennas, each with an aperture size of 1m x 0.8m. It achieves high resolution (<1m) and wide width (~500km) through four digital multi-beams.

Tri-Band GNSS Receiver System, TGRS
nThe radio waves emitted by satellites (including GPS and GLONASS) undergo refraction when passing through the ionosphere and atmosphere. Analyzing these refracted signals allows us to obtain data on temperature, pressure, humidity, and electron density in the atmosphere.
