Development of planar active phased array antenna for detecting and tracking radar

In this Paper, describes development of C-band Planar Active Phase Array antenna for Detecting and Tracking the target of small RCS. The antenna is designed with 14 sub-arrays (12 main and 2 side lobe blanking, about 3000 elements of transmit-receive unit) to properly synthesized transmit and receive pattern. Using a near-field measurements chamber, measured transmit pattern and Effective Isotropic Radiated Power (EIRP), also measured receive pattern and G/N. Receive pattern is implemented with Digital Beam Forming (DBF) by signal processing. The result of measurements shows a good agreement with Antenna design Specification.
