Abstract : A new scheme for radar target detection and discrimination, the radar waveform synthesis method, is investigated. This method consists of synthesizing aspect-independent excitation signals with particular waveforms which can be used to convolve with the radar return of the target to produce single-natural modes or the zero-mode of the target in the late-time period. When the synthesized excitation signals for a preselected target are convolved with the radar return from a wrong target, the convolved outputs will be significantly different from the expected natural modes or zero-mode, thus, the wrong target can be discriminated. The synthesized signals for single-mode excitation and the synthesized signal for zero-mode excitation (K-pulse) have been used to convolve with measured radar returns of targets. The results of convolution indicate the applicability of this new scheme in practice. (Author)
