Airborne Radar Clutter Modeling Techniques

Radar system simulation technology is widely used to become an important means of radar analysis, design, experiment and evaluation. Based on"xx radar simulation", this dissertation mainly discusses the design and application of its sub-systems: Clutter Generation and Signal Processing. Firstly, the program in this dissertation is rightly run in the matlab, and then it is transplanted to the C++.The main content and work in this dissertation can be summarized as follows:1. This dissertation analyzes the characteristics of phased array antenna for space-time adaptive processing. It introduces the methods for modeling and simulation of the Yagi-Uda phased array antenna and analyzes the antenna's amplitude weight and the tolerances of amplitude and phase.2. The coordinate transformation of plane: the transformation between plane geography coordinate system,plane coordinate system and antenna array system., and the simulation of the states of the plane.3. This dissertation uses the Chirp simulating the clutter. For simulating radar clutter fully, the gridding echo model is used to simulate clutter. The Sea and Ground clutter back scatter model are builded.4. Using the space-time adaptive processing restrains the clutter. Because the Computation of Space-Time optimal processor is huge, the dissertation uses the JDL and 3-CAP processing the echo.Based on the research of Radar simulation system, The dissertation gives a way of clutter generation and signal processing, and builds the model. It analyses the result, and the result prove that the model is right.
