The pulseWaveformAnalyzer is a MATLAB® App that lets you explore important properties of a signal such as its waveform, spectrum, and ambiguity function.

Use the ambiguity function to analyze waveforms. It compares range and Doppler capabilities of several common pulsed waveforms such as the rectangular waveform, the linear frequency modulated (FM) waveform, and the stepped FM waveform. It also shows ambiguity functions for several nonlinear FM waveforms and a phase coded waveform.

Visualize and interpret different waveform processing schemes and their tradeoffs in the Pulse Waveform Analyzer app.

Propagate a wideband signal with three tones in an underwater acoustic with constant speed of propagation. You can model this environment as free space. The center frequency is 100 kHz and the frequencies of the three tones are 75 kHz, 100 kHz, and 125 kHz, respectively. Plot the spectrum of the original signal and the propagated signal to observe the Doppler effect. The sampling frequency is 100 kHz.

The example illustrates the use of Swerling target models to describe the fluctuations in radar cross-section. The scenario consists of a rotating monostatic radar and a target having a radar cross-section described by a Swerling 2 model. In this example, the radar and target are stationary.

How waveform type affects a radar system's detection performance. The example considers the situation where a new performance goal is set for an existing radar system design. Since the old design can no longer achieve the desired performance, a new waveform is adopted. The example also shows how to model Swerling targets, simulate the return, and then detect the target ranges.

Construct a 5G urban macro-cell test environment and visualize the signal-to-interference-plus-noise ratio (SINR) on a map. The test environment is based on the guidelines defined in Report ITU-R M.[IMT-2020.EVAL] [1] for evaluating 5G radio technologies. This report defines several test environments and usage scenarios in Section 8.2. The test environment in this example is based on the urban environment with high user density and traffic loads focusing on pedestrian and vehicular users (Dense Urban-eMBB). The test environment includes a hexagonal cell network as well as a custom antenna array that is implemented using Phased Array System Toolbox™.

Create and display a multiplatform scenario containing a ground-based stationary radar, a turning airplane, a constant-velocity airplane, and a moving ground vehicle. The turning airplane follows a parabolic flight path while descending at a rate of 20 m/s.
