Abstract: PURPOSE: An image processing method and an apparatus thereof are provided to reduce coupling between a range direction variable and an azimuthal direction variable although the method is applied to a system requiring ultra wideband as a frequency band. CONSTITUTION: An image processing method includes the following steps of: generating dechirped data through the process of dechirping reflecting electromagnetic waves (S10); removing a phase component considering the distance between a target and an antenna from the dechirped data (S20); and processing a block signal about the data whose phase component is removed regarding a predetermined block area. The block signal process includes the following steps. The data is processed by Bulk RCMC (Range Cell Migration Correction) (S30). The data which is processed by the Bulk RCMC is converted from the distance-time domain to the distance-frequency domain (S40). The data in the distance-frequency domain is processed by azimuth deramping within a predetermined distance-frequency range (S50). CZT (Chirp ZTransform) is applied to the data processed by the azimuth deramping within a predetermined azimuth-frequency range (S60).

CONSTITUTION: A firm power sensing unit(110) senses firm power from a load dispatching center(20) with a preset cycle. A power switching unit(120) supplies or blocks power from a generator. If the firm power is not sensed, a control unit(130) blocks the firm power and supplies power from the generator. If the firm power is sensed, the control unit supplies the firm power and blocks the power of the generator. The operation mode of the generator is successively changed to a preheating mode, a starting mode, and a driving mode. The firm power sensing unit successively operates the generator at a cooling mode and a stopping mode if the firm power is sensed.
