Arbitrary Waveform Generator for Radar Simulator

  title={Arbitrary Waveform Generator for Radar Simulator},
  author={Abhishek Gupta and Anurag Mahajan and K. Aurobindo},
The research presents design and performance verification of a high-speed programmable pulse generator based on an integrated Direct Digital Synthesizer (DDS). The generator can produce pulses with an Arbitrary Waveform Modulation of instantaneous frequency up to 11 MHz. Its primary purpose is to generate various radar waveforms with user-defined pulse widths, PRTs, modulation bandwidths (if using modulation schemes within the pulse duration), and amplitude shaping. The waveforms are required… Expand
