Capabilities of noise radar in remote sensing applications

Nowadays noise waveform signals attract attention of radar engineers because they are inexpensive to generate both in analog and digital formats, covert, have good resistance against jamming and interference, are easily obtained using current microwave and RF circuit technology, spectrally very efficient and can share spectral bands without mutual interference, exhibit excellent waveform diversity characteristics. Coherent processing of noise signals enables to use them for phase and Doppler frequency measurements and for SAR imaging. Current work describes several radars showing current capabilities of noise radar technology such as shifts detection using Ka-band and X-band noise SAR, 3D SAR imaging and novel high dynamic range noise radars.
