Continuous Pseudonoise Signals in Remote Sensing Systems

Abstract:
This paper considers significant aspects of the pseudonoise phase-keyed signal usage in bistatic remote sensing systems. Main emphasis was made on continuous periodic and non-periodic (without interruption) pseudonoise signals in bistatic radar. This kind of signals has number of advantages over classic SAR signals - low peak power level, high noise and interference immunity, signal hiding, low noise level for other receivers systems and other. Point target response for the pseudonoise phase-keyed and pulse signals in bistatic synthetic aperture radar were visualised and compared.
