FMCW Radar Parameter Calculator (ADALM-PLUTO, 2.4 GHz Band) This project was developed as part of an undergraduate thesis in Electrical and Electronics Engineering. The goal is to calculate and analyze the key system parameters of a low-cost, SDR-based FMCW radar system, designed for use with the ADALM-PLUTO SDR operating in the 2.4 GHz ISM band.
Project Objectives Calculate fundamental radar metrics such as:
Range resolution
Maximum measurable range
Velocity resolution
Maximum detectable velocity
Evaluate detection capability using both:
Theoretical SNR requirement (Shnidman formula)
Physical system SNR from the radar equation
Simulate antenna gain and pattern using CST Studio Suite
Visualize performance trade-offs such as CRLB-based velocity uncertainty vs. range
Tools Used MATLAB: for parametric simulations and plotting
CST Studio Suite: to model and simulate antenna gain and directivity
Datasheets and Literature: AD9363, IEEE publications on FMCW radar design
Key Features Fully parameterized MATLAB code with clear definitions
Plotting of physical SNR vs. range and theoretical detection threshold
Calculation of minimum detectable range (dead-time limited)
Velocity CRLB visualization for Doppler resolution analysis
Code structure is modular and ready for hardware integration
Application Scope Educational demonstration of radar theory
Prototype development for short-range detection
Foundation for real-time implementation on GNU Radio + ADALM-PLUTO
Next Steps Transition to real-time implementation with GNU Radio Companion
Beat frequency extraction and Doppler FFT integration
Validation of target detection in real-world scenarios
