Abstract :
In this letter, a 16-element imaging radiometer using the digital beamforming technique is described. The system operates in the Ka-band in order to have high spatial resolution. The principle of an image reconstructing system is described. A series of experimental results is reported to demonstrate the effect of the system architecture.
