Why is the angular scanning range of phased array radar generally set to +-60? If the scanning angle is larger, what problems will it bring? Why?
When the scanning angle increases, if the scanning rate within the scanning radius remains unchanged, the scanning cycle time will increase, and the scanning interval will also increase relative to the same target. If the scanning period is maintained, the scanning rate within the radius will increase, which will lead to the obvious red shift or blue shift of electromagnetic waves and reduce the accuracy of judging the target position and speed.
