Modelling of Radar Targets and Radar Cross Section For Air Traffic Control Radars

Abstract

This paper studies the effect of target fluctuating models on ATC radar coverage such as swerling`s models 1 and 2, and swerling`s models 3 and 5. The results in this work show that swerlings case 5 (non-fluctuating target) has the highest range and swerling case 2 (fluctuating target) has higher range than swerling case 1 (fluctuating target). The signal to noise ratio obtained are claimed to be accurate to within 1dB for values of Hs >100. The deviation from the exact values of the signal to noise ratio for Hs <100 is rather large. It may be reduced, however, to acceptable  values by using certain correction of the swerling models and acceptable improvements in the SNR is obtained. The applications of this work sound widely espacially for ATC radar systems and militery applications for target classification and recognition. This work is performed by using C++ and object oriented programming and it could be used as a prediction package in the ATCR sitting.
