The Research Of MCPC Signals

Exploitation of high resolution radar techniques has always been the direction of radar research and development on both military and civil applications. The improvement of radar range-resolution not only facilitates detection of targets in high clutter, but also makes it possible to image and recognize targets.As a new kind of high-resolution signal, multicarrier phase coded radar signal has drawn attention due to a lot of advantage, such as perfect autocorrelation, flexible designing and easy processing. The work of this dissertation is focused on research of some key technics in signal design and processing of MCPC signal. The main content of the dissertation is summarized as follows:It gives a detailed description of the form of the MCPC waveform and its mathematical model, and analyses the formation and properties of phase coded sequence.It discusses the effect of signal parameters on autocorrelation, power spectra and ambiguity function in forms of single pulse and pulse train and compares different kinds of single pulse signals and pulse train signals.Take integrity of object information into condition, A two-dimension signal processing method which can make a measurement of the target's speed as well as the range is brought forward at the basis of waveform parameter design. And simulation in the background of HF multi-object with noise is taken.A comparison of signal properties, processing and antinoise detection performance is taken between MCPC and another two high range resolution radar signals: single carrier pulse coded signal and step frequency pulse coded signal.The work of the dissertation becomes the basic for the design and analysis of multicarrier phase coded wave in theory.
