The Application of Radar Homing Technology in Long-Range Accurate Guidance Missile

The restrict factors of final homing radar in long-range accurate guidance missile such as minimum final maneuvering distance, search area, electromagnetic salience, clutter and object discrimination were discussed in this paper. The main technologies for high resolution were put forward on the basis of the comparison of time domain one-dimension, frequency domain one-dimension, time and frequency domain two-dimension and synthetic aperture radar (SAR). At last, the principle model of an active/passive combined homing system and SAR radar device was given.
