Abstract

In this paper, the effect of different weather conditions on radar distance measurements was investigated experimentally. In current radar applications, the speed of the EM wave in the environment is accepted as the speed of light for distance measurements by radar. However, this speed varies in different weather conditions and is essential for sensitive radar applications. A radar system followed the target at a fixed distance to examine the changes in the speed of the EM wave due to the changes in the dielectric constant and conductivity parameters in different weather conditions. While measuring the distance, temperature, apparent temperature, relative humidity, and pressure were also recorded. Thus, erroneous distance measurements caused by air change could be detected. MLR, SVM, ANN, KNN and ANFIS models were used to estimate erroneous distance measurements caused by weather change. The results showed that the error in distance measurements could be estimated with great accuracy.
