Description
We develop a highly flexible real-time FMCW radar system for designing and testing different radar waveforms (e.g., triangular, sawtooth, sinusoidal) and radar signal processing algorithms without the need for extensive hardware modifications and fetching MATLAB codes, using low-cost SDRs. We control the shape of the waveform in real-time using an adaptive filtering method to improve radar performance metrics such as range resolution for integrated sensing and communications (ISACs) applications. To demonstrate real-time spectrum optimization, we use the gr-fosphor GNU Radio block for real-time spectrum analyzers (RTSA)-like spectrum visualization. We implement the joint receiver model in GNU Radio platform using the successive interference cancellation (SIC) algorithm to recover the communications bits constellations from the combined signal after the suppressing the predicted radar returns.
