Design, simulate, and test multifunction radar systems

Get Started:

Radar Applications

Simulate multifunction radars for automotive, surveillance, and SAR applications. Synthesize radar signals to train machine and deep learning models for target and signal classification.

Automotive Radar

Design probabilistic and physics-based radar sensor models. Simulate MIMO antennas, waveforms, I/Q radar signals. Generate micro-Doppler signatures, detections, clusters and tracks.

Multifunction and Cognitive Radar

Perform closed-loop radar simulation for multifunction radar systems. Model systems that respond to environmental conditions using waveform selection, pulse repetition frequency (PRF) agility, frequency agility, and interference mitigation.

Radar Systems Engineering

Simulate radar architectures that connect requirements to models and tests. Analyze radar link budgets. Predict detection and tracking performance in different environments.

Radar Architecture Modeling

With System Composer, develop architectures for multifunction radars that include subsystem componentization, traceability, and requirements-based testing.

Detecting and Tracking Statistics for Radar Equations

Explore designs using the Radar Designer app to populate radar equations for searching and tracking. Visualize results interactively to compare design choices. Determine detectability factors, receiver operating characteristics (ROC), and tracker operating characteristics (TOC) and generate range-angle-height (Blake) charts.

Environment and Clutter

Model and analyze radar propagation effects of land and sea clutter; atmospheric attenuation due to gas, fog, rain and snow; and lens effects losses. Characterize clutter using sea state and permittivity in addition to land surface with vegetation type and permittivity.

Radar Data Synthesis

Design radar sensor models; signal, detection and track generators; propagation channels; clutter; target radar cross section (RCS); and micro-Doppler signatures. Create realistic radar scenarios for airborne, ground-based, and shipborne platforms and ground-truth trajectories.

Radar Sensor Models: Signal, Detection, and Track Generators

Simulate radar data at probabilistic or physics-based levels of abstraction. For faster simulations, generate probabilistic radar detections and tracks to test tracking and sensor fusion algorithms. Alternatively, higher fidelity physics-based simulations start with transmitted waveforms, propagate signals through the environment, reflect them off targets, and receive them at the radar.

Radar Scenario Generation

Create realistic radar scenarios for airborne, ground-based, and shipborne platforms and targets. Model platform motion and orientation based on waypoints and trajectories or by simulating inertial navigation systems. Visualize and record the time evolution of the radar scenario.

Radar Signal and Data Processing

Design waveform libraries for multifunction radars. Develop algorithms for detecting targets in the presence of noise and clutter. Estimate range, angle, and Doppler responses for radar targets. Perform clustering and multitarget tracking on radar returns.

Waveform Libraries and Doppler Estimation

Create pulse compression libraries of waveforms with corresponding matched filtering and stretch processing. Estimate received signal parameters. Determine direction-of-arrival, detection, range, angle, and Doppler responses of targets and interference sources.
