Jupyter notebooks for radar systems simulation based on radarsimpy.

RadarSimPy is a radar simulation package built with python. Contact me if you are interested in this module.

There are 5 modules in this package:

1. Radar: Classes to define a radar system
   • radarsimpy.Transmitter: Radar transmitter
   • radarsimpy.Receiver: Radar receiver
   • radarsimpy.Radar: Radar system
2. Simulator: Radar baseband signal simulator
   • radarsimpy.simulator.simpy: Simulates and generates raw time domain baseband data (Python engine)
   • radarsimpy.simulator.simc: Simulates and generates raw time domain baseband data (C++ engine)
3. Raytracing: Raytracing module for radar scene simulation
   • radarsimpy.rt.lidar_scene: Simulates LiDAR's point cloud based on a 3D environment model with ray tracing
   • radarsimpy.rt.rcs_sbr: Simulates target's radar cross section (RCS) based on the 3D model with ray tracing
   • radarsimpy.rt.scene: Simulates radar's response signal in a 3D environment model with ray tracing
4. Processing: Basic radar signal processing module
5. Tools: Receiver operating characteristic analysis

• numpy

• axis (m): [x, y, z]
• phi (deg): angle on x-y plane. Positive x-axis is 0 deg, positive y-axis is 90 deg
• theta (deg): angle on z-x plane. Positive z-axis is 0 deg, x-y plane is 90 deg
• azimuth (deg): azimuth -90 ~ 90 deg equal to phi -90 ~ 90 deg
• elevation (deg): elevation -90 ~ 90 deg equal to theta 180 ~ 0 deg

• axis (m): [x, y, z]
• yaw (deg): rotation along z-axis. Positive yaw rotates object from positive x-axis to positive y-axis
• pitch (deg): rotation along y-axis. Positive pitch rotates object from positive x-axis to positive z-axis
• roll (deg): rotation along x-axis. Positive roll rotates object from positive z-axis to negative y-axis
• origin (m): [x, y, z]
• rotation (deg): [yaw, pitch, roll]
• rotation (deg/s): rate [yaw rate, pitch rate, roll rate]
