A perspective on two decades of fundamental and applied research in electromagnetic scattering and high frequency ground wave radar on the Canadian East Coast

While a vast amount of literature, dating back at least six decades, exists on the problem of the scattering of electromagnetic (e-m) radiation from randomly rough surfaces, important advances have been made within the Canadian context over the last twenty years. A new theory for dealing with rough-surface scattering problems has evolved from the work of researchers at Memorial University of Newfoundland. Primary incentives for the work lie in its relevance to remote sensing in the harsh environment of coastal and offshore resource development as well as the surveillance of Canadian interests within the "200-mile limit". Several applications of the theory to ground wave radar operations on Canada's East Coast have resulted. Some of the most significant theoretical and applied developments are briefly summarized here.
