Research on Height Finding Technique for Dual-frequency Radar

To solve the problem of height finding of dual-frequency radar, based on the phase interference theory, the height finding technique of dual-frequency radar is studied. Firstly, the basic principle of phase interference angle measurement is given in the paper, and the corresponding problem of phase blur in the use of dual-frequency radar height finding is analyzed in detail, then the resolving phase difference ambiguity method which is based on Chinese Remainder Theorem (CRT) is provided. Finally, the height finding precision is discussed. As a result, it is a feasible height finding technique of dual-frequency radar, of which the validity is also proved by the simulation of computer.
