Abstract

Today’s air-target missiles have advanced built-in systems for target seeking and navigation. By the use of radar, the missile can detect and track a target from a long distance.Radar is an electromagnetic system for detecting, locating and sometimes for recognition of target objects, which operates by transmitting electromagnetic signals, receiving echoes from target objects within its volume of coverage, and extracting location and other information from the echo. In this paper, controlling and predicting of the Radar Cross Section (RCS) of a missile shaped object is presented. The prime effort is to find the presence of complex and arbitrary objects by monostatic radar and utilizing their RCS signatures obtained by performing its simulations in MATLAB to classify the objects of the targets. The signatures are observed in MATLAB for further development to find accurate RCS of a missile shaped object. Results shows that simulating the RCS for the complex circular cylinder with two perfectly conducting circular flat plates on both ends with linear polarization and frustum with H=40cm, r1=15cm, r2=30cm. RCS in dB(m2) starting at 25dB (m2) and end at 25 dB (m2) for data. But the RCS measured in dB (m2) at 90° of the aspect angle reached 20dB (m2), and at around 180° of the aspect angle a rise in RCS of 27 dB (m2) was observed. From the overall results of the simulation, as researches, radar designers can be faithfully advised on the behaviour, range, the effective capture area, and the minimum detectable signal of RCS of missile shaped object.
