Abstract

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 to be generated in synchronization with the radar system’s timing signals. It is desirable to generate pulsed waveforms at higher Ifs; the upper limit is determined by the FPGA’s master clock. The waveform generator can be used as a transmit unit as well as a radar return signal simulator. Multiple channels on the board can provide simultaneous modes.
