Simulation of radar signal in fog environment

Use matlab to simulate radar signal propagation attenuation in fog environment, especially in distance and power.

This works based on Phased Array System Toolbox.

Radar parameters

• Frequency: 24GHz.
• Chirp period: 5e-4s.
• Bandwidth: 500MHz.
• Targets distance: 5.23 18.23 31.20m.
• Targets speed: -0.7 0.47 0.5
• Targets RCS: 0.3 0.3 0.3

Code Explanations

1. Whether the range_max and v_max settings are within the radar parameter limits.(if so, the sample rate is 2*Bandwidth, nothing to do with range_max or v_max)
2. The ChirpLen*resolution is the max range can be detected.
3. The ChirpNum*resolution is the max speed can be detected.
