Robust Modulo Remaindering and Applications in Radar and Sensor Signal Processing.

摘要

This report describes the main research achievements during the time period cited above on the research project in the area of digital signal processing. The main achievements include robust reconstruction of large integers (one or two simultaneous integers) from their remainders/residues modulo several moduli, and the maximal dynamic range for the determinable integers of two from their remainders modulo a set of moduli. It includes their applications in phase un-wrapping in SAR imaging of moving objects, high frequency determination from multiple undersampled signals with very low sampling rates of sensors, and error correction coding. This report also includes a new OFDM SAR imaging by using sufficient cyclic prefix (CP) at transmitter and a non-matched filter imaging algorithm at receiver called interrange- cell interference (IRCI) free range reconstruction.
