Use of a stretch waveform in a jamming environment with closely spaced objects such as surface vessels or fighter aircraft is presented. Adaptive cancellation in the sub-banding architecture improves the system cancellation ratio on large sub-array digital receiver systems. Detailed hardware models that capture key system requirements are described. Key model components are system aperture, receive chain with beamforming and digital data processing elements. The model takes error levels at array elements (e.g., quantization and beam pointing), digital receiver (e.g., amplitude and phase errors, time-delays, and aperture dispersions). System performance is evaluated via high-fidelity models and is characterized by the computing system's cancellation ratio.
