Entry into the field of radar cross section measurements or synthetic aperture radar (SAR) algorithm development is often difficult due to the cost of high-end precision pulsed IF or other precision radar test instruments. A low-cost entry-level alternative was developed in order to provide an intermediate step between high-end high precision radar systems and ad-hoc spare parts systems. The system developed is a frequency modulated continuous wave radar utilizing homodyne radar architecture. Transmit chirp covers 8 GHz to 10.5 GHz with 18 dBm of transmit power. Due to the fairly wide transmit bandwidth; this radar is capable of better than 12 inches of range resolution. The dynamic range of this system was measured to be 60 dB. Such a low-cost, high resolution X-band laboratory radar system could be utilized as a linear rail SAR, inverse SAR, or for motion compensation experiments
