This paper addresses some of the potential opportunities for achieving advances in radar systems and technology. It is not a summary of current interests in radar, nor is it a forecast of what 'will be', but is speculation about what 'could be' based on the limited experiences and personal biases of the writer. Included are the replacement of existing radars that have been in use for some time, 'on-the-shelf' concepts and demonstrated technology that have yet to be employed, a few new directions that might offer capabilities that do not currently exist, and areas of basic technology that could be further explored to provide new understanding and new capabilities. Although much is included in the paper, it is not meant to be an exhaustive enumeration of the many possible directions for future radar.
