| Abstract: | The basic principles of weight Linear Frequency-Modulated (LFM) signals and NLFM signals are introduced. The waveforms of two frequency-modulated signals are designed based on four kinds of functions with large time-bandwidth products. A simulation is performed. The pulse suppression performance of different designed signals is given according to the simulation. The simulation results are instructive to choose waveforms for large time-bandwidth product signals. |
