“…We have carried out experiments on generation of 3D tomographic imaging using Ka-band continuous waveform noise radar [4] and two antennas with beam synthesizing [3]. In these experiments we have shown generation of 3D tomographic images and capability of focusing the scene targets responses in 3D space using the proposed approach.…”

“…Use of random waveform delivers such benefits as absence of range ambiguity and improving immunity against external electromagnetic interferences [1][2][3][4].

“…However, unlike any earlier work, in the paper the millimeter wave tomography is implemented with the help of noise signals and antenna of a new type: Antenna with Beam Synthesizing [3]. To demonstrate implementation of millimeter wave tomography with the help of Ka-band Ground Based Noise SAR [4] we have carried out indoor experiments aimed on obtaining of 3D tomography images of a laboratory room interior. The approach suggested opens up a new direction in microwave tomography which may be applied for design of millimeter wave tomography systems for content inspection of closed boxes, hidden monitoring of a closed room [5], etc.…”

Conventional SAR generates 2D image using combination of range compression and 1D aperture synthesis. The range resolution of such 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 in both dimensions to obtain resolution along two angular coordinates. In combination with pulse compression it gives 3D resolution. We suggest using MIMO principle in combination with SAR approach to generate 3D coherent radar images. For that, two linear synthetic apertures used -one for transmit antenna and another for receive one. Spatial scanning with those antennas is performed in the way which provides data similar to the ones obtained from 2D scanner. The paper describes the approach and presents results of its experimental test using Ka-band noise waveform ground based SAR.

“…Generally noise signal with correlation processing is known to be able to preserve phase information and, hence, is applicable for measurement of Doppler frequency shift [8] and for SAR imaging [9]. Validation of possibility to use the proposed approach for SAR imaging can be also made by measurement of Doppler signal from a moving target using the AWGbased stepped frequency noise radar.…”

current paper deals with radar design obtained by combination of two approaches: stepped frequency radar and noise radar for the purposes of SAR imaging. The idea of operation of such combination is following: instead of single frequency signal a narrowband noise signal is radiated in a stepped frequency radar. The processing is done in the same way as in usual stepped frequency radar. Noise modulation will lead to limitation of area within which the radar is sensitive by the correlation length of the noise signal. Analog filter in the receiver will filter out fluctuations caused by the targets outside the noise signal correlation interval. This gives possibility to make a radar using stepped frequency concept but with limited sensitivity zone. This can be helpful for omitting such drawbacks of stepped frequency approach as presence of range ambiguities, low electromagnetic compatibility, high probability of interception and low interference immunity. Besides, it preserves such desired quality of stepped frequency radar as ability to generate high resolution range profiles using a narrowband receiver. This solves problem of lack of ADCs with both high depth and sampling rate which leads to difficulties in design of high performance noise radars using conventional approach. The aim of the paper is to describe the approach, to present results of experiments aimed on detection of Doppler signal using the approach and limitation of observed ranges via variation of noise modulation bandwidth.

Noise waveform SAR generates 2D SAR images of a scene. Advanced radiometric SAR imaging provides information on the objects thermal radiation, angular coordinates and even range. The brightness temperatures of rough and smooth surfaces are different. An active, noise waveform, operating mode of bistatic radiometer, based on antennae with beam synthesis, is considered with respect to the roughness criteria. The optimal and quasi-optimal algorithms for fusion of radiometric and SAR images are presented. The method suggested and results obtained may be used in environmental and security applications.
