[en] This paper presents a low-cost, compact and modular radar frontend, operating at 24 GHz, specifically designed as an extension for commercially available software-defined radios (SDRs). The system enables realistic cognitive and automotive radar experimentation by supporting flexible waveform generation and seamless SDR integration. Its small footprint (25×9×4 cm) and modular design allow rapid reconfiguration for various test scenarios. Experimental characterization confirms linear system behavior, stable local oscillator (LO) performance and acceptable LO leakage. Over-the-air (OTA) measurements demonstrate sufficient output power and coherent loopback capability. This platform offers a practical and scalable foundation for prototyping advanced radar systems, bridging the gap between laboratory-grade setups and field-deployable cognitive radar (CR) testbeds.
