Radar measurement accuracy is mainly dependent on the signal-to-noise ratio (SNR). SNR variation of the same target is related to fluctuating target radar cross-section (RCS) that is known as Swerling RCS model. Radar measurement accuracy is an important parameter to design a radar system or to analyse its performance. More useful measurement accuracy formula than the previous research that is sensitive to the detection threshold is proposed. To investigate the measurement accuracy affected by Swerling model, the relative standard deviation is defined to compare the value of the previous research with the proposed value.
