Research On Algorithms Of The Motive Single-Station Location

In the modern warfare, radar countermeasure is an important means to achieve military superiority. It is an essential component for every kind of weapon systems and military targets to ensure themselves survival and development. Passive location does not emit electromagnetic wave itself and works a far distance range with a good concealment. Whithout complex time synchronization and data fusion between stations,people pay great attention to single-station location. Motive single-station is moving ,so it introduced the changing of the phase, angle, time and other multiple parameters. It can analysis a variety of algorithms to improve the precision facilitately.Based on fixed radiation sources, this thesis discusses issues such as filtering algorithms, location theory, and how to establish the motive single-station location models. Especially, we study the algorithms with high precision and strong anti-interference ability. We study several methods, including time changing, phase changing rate and power rate. Describing the principles of various methods in detail, this thesis abstracts entities, establishes the establishment of two-dimensional and three-dimensional, simulates the mathematical models. At the same time, we dicuss the location precision and the effect of signal to noise ratio relationship of all the mentioned location algorithms, whereby analysis the various advantages and disadvantages.
