Experimental Investigation of Factors Affecting Stability of Interferometric Measurements with Ground Based Noise Waveform SAR

Application of ground-based SAR and differential interferometry technique is often used for monitoring manmade objects aiming detection of their structural changes. Recently Kaband Ground Based Noise Waveform SAR has been developed [1] which may be applied for the above monitoring. The paper is devoted to investigation of stability of Noise Waveform SAR. Monitoring of a simple construction has been carried out. The related measurements enabled estimating the accuracy of differential phase measurements using the above Ka-band Noise Waveform SAR. In the paper we present some results of the experiments and their explanations. Keywords—Noise waveform, noise radar, SAR imaging, differential interferometry.
