The history of precision guidance technologies was reviewed, and the challenges and main developing trends of imaging and detecting technologies for precision guidance were illustrated. Combined with the recent developments of the emerging technologies such as terahertz, quantum and metamaterial, the backgrounds, developing venation, basic principles and advantages of three typical advanced imaging and detecting technologies, namely, terahertz radar, quantum radar and metamaterial radar were expounded. These advanced techniques may have the potential to provide feasible approaches for precision guidance technology to overcome the challenges brought by the future new warfare form. The analysis results will provide some positive guidance and is of significance for improving the strike and intercept effectiveness of the precisionguided weapon systems.
