Abstract
This paper addresses the impact of limited oscillator stability in bi- and multistatic SAR. Oscillator noise deserves special attention in distributed SAR systems, since there is no cancellation of low frequency phase errors as in a monostatic SAR, where the same oscillator signal is used for modulation and demodulation. We show that uncompensated phase noise may cause a time variant shift, spurious sidelobes, and a widening of the impulse response, as well as a low frequency phase modulation of the focused SAR signal. Quantitative estimates are derived analytically for each of these errors based on a systems theoretic model taking into account the second-order statistics of the oscillator phase noise.
