Detection Performance Analysis And Combat Efficiency Estimation Of Airborne Fire-control Radar System

The detection performance and combat efficiency of radar system is analyzed in this paper. By combining variety parameters of radar system, many kinds of radar system can be compared .The paper analyzes some typical parameters of radar system theoretically, convenient for analyzing the dynamic performance of radar system.First, the max range of detection of radar in free space is analyzed in this paper theoretically. On this base, the paper then analyzes the formula of the max range of detection in clutter, jamming and anti-jamming respectively. The computation is done by program.Second, this paper analyzes the Time-Frequency distribution of the clutter from airborne Pulse Doppler Radar (PDR). The side-lobe clutter, which is the main factor to influence the PDR, is analyzed and calculated. Based on the simulation of typical geometry of the land, we analyze and discuss the side-lobe clutter and concluded that the DFT of can be considered as the phase of the coho . We use this conclusion in our program.The last, the principle and the precision of the detection of range, speed and angle is analyzed and discussed theoretically. Using the precision formula of rectangle pulse waveform, we programming the software to accomplish the computation simulations.Otherwise, the conception and the academic formula of the detection probability and false alarm probability of radar is analyzed, and the computation is done by program.The main contribution of this paper is that it offers the software to analyze the detection performance and the combat efficiency of radar system taking advantage of Visual C++6.0.The software has very well graphics visualize output interfaces. The software can be used to expediently compare the detection performance of radar in existence, calculate and compare the max range and the detection precision of different radar under varying complex environment, calculate the radar detection probability and the radar false alarm probability. Some new analyzing module can be added in this software easily.
