Constant False Alarm Rate (CFAR) detection refers to a common form of adaptive algorithm used in radar systems to detect target returns against a background of noise, clutter and interference. The role of the constant false alarm rate circuitry is to determine the power threshold above which any return can be considered to probably originate from a target as opposed to one of the spurious sources. If this threshold is too low, then more real targets will be detected, but at the expense of increased numbers of false alarms. Conversely, if the threshold is too high, then fewer targets will be...

Radar Cross-Section (RCS) is a measure of how detectable an object is by radar. Therefore, it is called electromagnetic signature of the object. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. In this book we simulate the RCS to represent the specified targets under different conditions such as aspect angle and frequency. This model is use for performance evaluation of radar. Next the data of radar target is simulated. The models adopted are swerling ones. firstly we develop ideology for the simulation and...
