Abstract

The modelling and performance evaluation of ground based monostatic radar surveillance system presented in this paper is analysed in terms of system performance results, input data of the radar system and its operating mode. Radar equations are derived to obtain the minimum detection signal (Pmin), system loss (Lsys), minimum signal-to-noise ratio (SNR)min and maximum detection range equation (Rmax) respectively. Radar parameters such as transmit peak power (Pt), antenna gain (G), radar cross section (RCS), bandwidth (B), and other parameters are analysed in the radar equations. Radar system losses (Lsys) are accounted into the modified radar equations and calculated to be 21.1 dB. The modified radar equations with Pt = 15 kW, and Rmax = 500 km, also gives a significantly lower value of SNR = 27.0 dB. Analysing the radar performance, MATLAB simulation program is used to evaluate the radar performance equations with different parameter values. Target detection radar signal is a difficult problem when the SNR is low, thereby causing the constant false alarm rate (CFAR) processor to adjust threshold. Simulation results are presented respectively.
