The physical basis and operational implications of an expanded palette of missions for HF radar

The Atlanta AESS/GRSS joint chapter is pleased to host Dr. Stuart Anderson on Wednesday, May 27th. The talk will be held in Midtown Atlanta and streamed to Cobb County. Speaker: Dr. Stuart Anderson, University of Adelaide, University College London Title: The physical basis and operational implications of an expanded palette of missions for HF radar Abstract: The remote sensing and surveillance capabilities of HF radars are well established, with roughly a dozen military grade skywave radars in operation by nation states, around twenty line-of-sight HF radars carrying out observations of the high latitude ionosphere, several hundred HF radars exploiting the surface wave mode of propagation, and a number of radars exploiting hybrid modes. By far the most common tasks addressed by these radars are those relating to the measurement of ocean surface currents and sea state; radar products of varying degrees of detail and fidelity are routinely generated by many operational radar systems. It might be thought that the maturity of the basic concept underlying the technology, now in its seventh decade, would have led to a corresponding stability in the palette of missions that these radars address, and, indeed, that is largely the case. Moreover, the evident satisfaction of many scientists and radar clients with the present family of products has tended to reduce incentives for major refinement and expansion of the existing radar capabilities, with attention focusing instead on the practical applications of the standard products, civil and military. This state of affairs is understandable, but not inevitable. A number of studies, especially some undertaken in the context of military radars, have explored ideas that could dramatically expand the capabilities of HF radar in its remote sensing roles, as well as its surveillance missions. The viability of several of these ideas has already been demonstrated experimentally, some are presently being investigated, and others are being modelled in detail to assess their merit. Almost all have implications for radar design, operating procedures and signal processing. In this talk I shall describe some examples of these frontier applications of HF radar and indicate how their successful implementation can be achieved.
