Abstract :
This paper investigates the performance of pseudo-noise (PN) sequences as pulse compression waveforms in the radar imaging of distributed targets. Multiple transmitter schemes such as multi-static synthetic aperture radar (SAR) and multi- baseline interferometric SAR (InSAR) provide high resolution images for remote sensing applications at lower costs. PN sequences are a natural choice for such systems. The performance of different PN coding schemes such as the maximal length sequences (m-sequences), Gold sequences and shifted m-sequences are compared.
