Research on Simulation of Radar Return from Extended Target

Simulation of radar return from targets is an important part of radar system simulation and it is developing fast these years. Although there are already many mature theories on simulation of radar return from targets, these theories mainly aim at point targets and often simply describe an extended target as synthesis of many point targets. There is little theory to describe detailed methods of how to judge the position of extended targets compared to the beam of radar and how to divide extended targets into point targets and synthesize radar returns from them. This thesis found the methods, described them in detail and proved them with simulation. Using these methods, we can simulate radar return of extended targets more veraciously and provide more reliable data for analysis, designation and test of radar systems.
