The paper gives a detailed overview of the algorithm of image reconstruction by using trajectory Doppler signal on the circular motion of the locator and the circular aperture synthesis. The monochromatic signal is considered. The offered method of reconstruction is non-projection one. In contrast to projection method it works equally well both in the near-field and far-field regions relative to the object aperture. Results of the model image reconstruction of single-point and three-point objects are represented. The interference on structures of reconstructed image and structures of ring spectra is shown.

We consider synthetic aperture radar system using ultra-narrowband continuous waveforms, which we refer to as Doppler Synthetic Aperture Radar (DSAR). We present a novel image formation method for bi-static DSAR. Our method first correlates the received signal with a scaled or frequency-shifted version of the transmitted signal over a finite time window, and then uses microlocal analysis to reconstruct the scene by a filtered-backprojection of the correlated signals. Our approach can be used under non-ideal imaging scenarios such as arbitrary flight trajectories and non-flat topography. Furthermore, it is an analytic reconstruction technique which can be made computationally efficient. We present numerical experiments to demonstrate the performance of the proposed method.
