Abstract
The authors describe an arc projection algorithm applied to radar imaging in a near-field case. In a close area, the samples of echo signal are no longer pure frequency-domain data due to wavefront curvature. In such cases, it is not proper to process echo signals by utilizing traditional imaging methods. The authors propose the idea of near-field correction. Combining it with the convolution backprojection (CBP) algorithm, an arc projection algorithm is obtained. Computer simulation results obtained by processing echo signals in the near-field using the arc projection algorithm and the conventional CBP algorithm are presented and compared.<>
