WEATHER RADAR APPARATUS, AND CONTROL APPARATUS AND CONTROL METHOD THEREOF

摘要

According to an embodiment, a weather radar apparatus includes the following elements. The feature quantity calculator calculates, based on the weather information for the targets in an observation range, a feature quantity of each of the targets. The allocator performs transmit allocation in pulse unit or pulse pair unit to the targets based on the feature quantity. The allocation halt instruction unit instructs the allocator to halt transmit allocation to a target satisfying a certain condition. The beam controller generates a control signal to control a beam direction and transmit timing based on a result of the transmit allocation. The transmit signal generator generates a transmit signal based on the control signal. The array antenna transmits the transmit signal.
