Effect of frequency diversity on SAR ATR

Synthetic aperture radar (SAR) based automatic target recognition (ATR), has been one of the demanding usages of airborne radar systems. With the developments in the field of hardware, more complicated radar systems can be deployed on aerial platforms. This opens the possibility of using different advanced versions of radar systems, like multi-band radars, multi-polar radars and multi-static radars. In the current paper, we report the preliminary experiments studying the effect of frequency band on SAR ATR performance. In this pilot study we have used the well accepted MSTAR SAR database. The results show that even though bandwidth is kept the same, the ATR performance strongly depends on the central frequency.
