Ka-Band Ground-Based Noise Waveform SAR

Abstract

We present main results of design and investigations of Ka-band ground based interferometric SAR which uses continuous noise waveform as a probe signal and may operate in both monostatic and bistatic regimes. Synthetic aperture antennas enable to design a portable, light weight, easy to mount device with high speed of operation suitable for SAR imaging in quasi-real time while Ka-band noise waveform signals provide all-weather high resolution, high electromagnetic compatibility and interference immunity. Experiments have shown a rather high stability and repeatability of the measurements due to both the high quality of the equipment and advanced signal processing methods. The SAR system designed is an innovative instrument for solving new tasks of precise remote monitoring of various large objects, such as sealing of big halls, dams, bridges, TV towers, hangars, etc.
