Description: Topic: Product Processing Technique for Antenna Arrays and Interferometry
Location: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A
Abstract:
Conventional array processing techniques utilize linear processing techniques to combine different signals from multiple array elements or tracks. In this project, a new product processing technique is proposed for both antenna arrays and interferometry. This new product processing technique is called the Antenna Product Processing (APP) technique for antenna arrays and Interferometric Product Processing (IPP) for SAR interferometry. The APP technique is shown to emulate the performance of a larger antenna array using measurements from a smaller antenna array. The proposed method uses measurements from smaller antenna arrays and produces Direction-of-Arrival estimates commensurate with results produced by linear processing of measurements from much larger antenna arrays. The IPP technique is shown to emulate the performance of a longer interferometric baseline with measurements from a smaller interferometric baseline. Simulations show that the proposed method may use smaller interferometric baselines and produce phase estimates commensurate with results produced by linear processing of measurements from much longer interferometric baselines. For separating scattering from multiple scattering centers, IPP performance is comparable to linear processing of measurements from much larger baselines. The sensitivity for APP and IPP techniques to noise is also investigated.
