Frequency scanning antenna

The invention embodiment referring to acoustic radar system for improving, and for with a frequency scanning radar system is a. In a secondary, the improved specifcially a is used for controlling frequency generator frequency scanning radar controller; The frequency the generator and generating multiple groups of signal, each group of signals with different frequencies eigen and the multiple of the signal of the speed transmission, and radar controller setting and base eigen frequency and speed. The invention the specifcially capable of the pulsed radar, wherein each group of sensor comprises device of impulse signal, and each pulse signal of the repeat speed repeat. The radar controller setting and the signal generating eigen frequency modifying repeat speed. The invention specifcially alternative a frequency for regulating radar system, wherein each group of sensor comprises a sequence of regulating pattern. Radar controller setting and contacting according to the regulating pattern for wideband signal eigen frequency modifying setting.
