Abstract : A new scheme for radar detection and discrimination, the radar waveform synthesis method, is investigated. This scheme consists of synthesizing the aspect-independent, incident radar signal which excites the target in such a way that the return radar signal contains only a single natural mode of the target in the late-time period. When the synthesized incident signal for a preselected target is applied to a wrong target, the return signal will be significantly different from the expected natural mode, thus, the wrong target can be discriminated. At alternative scheme is also developed to extract the single-mode return signal by convolving, using a computer, the required incident radar signal for the single-mode excitation with a return radar signal from the target excited by an arbitrary incident radar signal. A study on the synthesis of the K-pulse has been initiated. The progress on the experimental setup and study is reported. (Author)
