Digital Radar Transceivers providing precise digital control over waveform amplitude, frequency and phase is critical for modern Phased Array Radar systems. A Plug-and-Play (PNP) Transceiver was developed to support the Air Force's objective to develop a Hybrid Multiple Input Multiple Output (MIMO) Phased Array Radar (HMPAR) system, where the full array is partitioned into multiple sub-arrays which can be driven by mission specific waveforms. This PNP Radar Transceiver has been integrated with the Lockheed Martin's Portable Search and Target Acquisition Radar (PSTAR) antenna array. Advanced Radar capabilities including transmit-receive digital beam-steering, direct digital L-band receiver and real-time digital signal processing with the integrated system have been successfully demonstrated. This paper discusses the overall PNP Radar Transceiver concept and highlights the successful phased-array test results when integrated with the PSTAR array.
