Pulsed Waveforms
Amplitude, phase, and frequency-modulated pulse waveforms
The Phased Array System Toolbox™ provides several narrowband pulsed waveforms. Waveforms in the toolbox are all complex baseband signals. Use pulsed waveforms in radar and sonar applications.

Topics
Pulsed Waveforms
- Rectangular Pulse Waveforms
Simplest waveform has constant amplitude over pulse duration. - Linear Frequency Modulated Pulse Waveforms
LFM pulse waveforms increase time-bandwidth product and improve target detection. - Stepped FM Pulse Waveforms
Stepped frequency pulse waveforms increase time-bandwidth product and improve target detection. - Phase-Coded Waveforms
Phase-coded waveforms have good range resolution. - Waveforms with Staggered PRFs
Staggered pulse-repetition frequency waveforms remove Doppler ambiguity.
