Item ANALYSIS AND QUANTIZATION OF RANGE ERROR OF MODULAR FMCW RADAR AT C BAND(2022-02-28) Abdulrazigh, Mahfoud Y. A.; Kara, AliThis thesis presents the experimental analysis of range error of modular FMCW (frequency modulated continuous wave) radar operating at C-band. FMCW radar is a type of radar where frequency modulation is used in signal transmission. FMCW radar can measure both range and speed of targets. One of the problems in the design of modular FMCW radar is errors due to time delays in components and/or modules such as cables, PA, LNA and antenna (Measurement Instrumentation Delay-MID). Then, MID is taken into account to improve the accuracy of range measurement, and range error is quantized. Time delay (MID) causes frequency offset in measured beat frequency resulting in range error. Therefore, the resulting frequency offset of the radar is estimated and quantized experimentally. In this way, a mean error of about 11cm was achieved within 9m range measurements for C Band modular FMCW radar.
