The paper is devoted to design and testing of a reconfigurable Ka-band GB NW-SAR. Its design is based upon new synthetic aperture antennas and noise radar technology. Results of outdoor trials are presented for both SAR imaging and differential interfrometry measurements. Synthetic aperture antenna suggested and designed transmit/receive units are briefly(More)
We describe Ka-band MIMO Noise Radar and present preliminary results of its experimental validation using bistatic ground based SAR. The range resolution in radar 3D imaging is determined by power spectrum width of the transmitted signal, while its cross-range resolutions are defined by 2D aperture dimensions. We apply MIMO concept with time-division to(More)
There is a growing interest to using of Ground Based SAR for detection of small shifts of various objects. Such equipment can be used for detection of changes in buildings, towers, bridges and natural objects. This can help to predict and prevent possible catastrophes. We have elaborated SAR system capable of detecting such changes using noise radar(More)
The paper is devoted to coherent radiometric imaging systems. The investigated systems may be considered as a version of bistatic noise waveform radar with synthetic aperture having external reference. Reference signal in this imaging system is received from the investigated object using auxiliary receiver. Although a number of theoretical studies on(More)
Conventional SAR generates 2D image using combination of range compression and 1D aperture synthesis. Range resolution of this approach is determined by the signal spectrum width, while cross-range resolution is defined by the synthetic aperture length. 2D aperture synthesis implies movement of antenna along 2D aperture and cross-range compression technique(More)
We describe MIMO approach to implementation of radar tomography and present preliminary results of its experimental validation using Ka-band noise waveform ground based SAR. The range resolution in radar tomography is determined by power spectrum width of the transmitted signal, while cross-range resolutions are defined by 2D aperture dimensions. We apply(More)
MIMO approach to implementation of radar tomography is described and preliminary results of its experimental validation using Ka-band noise waveform ground based SAR are presented. MIMO concept with time-division to of Tx/Rx channels is applied to emulate 2D aperture synthesis combined with range resolution due to wideband random signals. Two linear(More)
The paper is devoted to experimental investigation of coherent radiometric imaging in azimuth-range plane. The Ka-band radar system suggested is a version of bistatic noise waveform SAR (Synthetic Aperture Radar) using two antennas with pattern synthesis and additional receive channel used as a reference signal. Indoor radiometric imaging has been validated(More)
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(More)
Works concern to computer modeling of immunity of noise and LFM radars affected by single-frequency interference that is its influence on a form of output correlation effect depending on time of accumulation. The different influence of single-frequency interference is examined for both noise and LFM-signals as well as SAR-image. Advantage of application of(More)
