Investigation and Design of Distributed Subarray Smart Antenna System Using 1×8 Switched Butler Matrix For Phased-Array Radar Applications
As the target radar cross section (RCS) continuously decreases, the need for high resolution high-gain radar increases. One approach to high resolution is to use distributed subarray antennas (DSAs), because of limited surface available on many radar platforms. In this paper, the investigation and design of distributed subarray smart antenna system using 1x8 switched butler matrix has been introduced and analyzed. The proposed butler matrix measured radiation characteristics of the smart radar antenna system structure are obtained to demonstrate the performance which has isolation up to -27 dB and coupling up to -52 dB. The proposed smart radar antenna system provides high-resolution with highspeed data collection simultaneously and show the trade-off in performance and cost for several possible antenna concepts to meet the requirements for phased-array radar applications.
