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.
