An investigation of the feasibility of extending an existing radar target identification scheme to the case of naval vessels is reported. The existing scheme is based on the complex natural resonances of a target associated with transient responses synthesized from multiple frequency scattering data. To this end, multiple frequency scattering data of good model targets of various vessel classes in a simulated ocean environment are reported. From these data special target response waveforms are generated and natural resonances extracted. Results are given showing the identification potential of both the response waveforms and the complex natural resonances. In a concluding section recommendations are made for a logical continuation of the research effort. (Author) 收起
