This paper covers the concept, architecture, development and demonstration of a Smart Antenna Software Radio Test System (SASRATS). SASRATS was designed and developed as a functional and flexible system to facilitate the field testing of space-time processing architectures and algorithms. It also facilitates the correlation between theoretical, simulated and measured performance. The SASRATS architecture has the capability of real time implementation of signal processing algorithms. The paper also covers the testing, debugging and calibration of SASRATS prior to commissioning. The paper will cover the field testing and verification of two space processing algorithms. It is used to verify the work done by the authors and others in the field of signal enumeration and blind beamforming.
