✦ Synopsis
An incoherent imaging of a conducting cylinder illuminated by the time-harmonic plane wa¨e is obtained ¨ia the backprojections of the incoherent intensity patterns, which is acquired by a¨eraging out the multifrequency intensities of the total field scattered from this object in the circular rotational measurement configuration. The multifrequency effect is shown numerically, and is interpreted analytically by the mutual coherence function defined in the frequency domain. This imaging method is ¨alidated by imaging circular and elliptic conducting cylinders, and the conditions for obtaining better images are in¨estigated.
