Extended Noise Analysis Model of CW-type Radar Sensors with IQ Down-Conversion

Original language description

CW-type structures, especially those in the form of small sensors, are amongst the most frequently employed radars in security applications or the automotive industry. The range and operational reliability of these sensors strongly depend upon their noise parameters which this paper examines by extending previously published works and considering all potential inner noise sources to create a complex noise model of the radar family in question here, including commonly used IQ signal processing. The noise sources in question cover local oscillator amplitude-noise and phase-noise, noise from an RF signal path, and noise from a low-frequency signal path. The resulting noise model was verified by practical measurements which included two different local oscillator type, two different low-frequency bandwidths and several different time-delays of the cross-talked signals. In all cases, the agreement between theory and measurement was within the estimated limits. The developed model is applicable for noise analysis and the design of all common CW-type radars
