目標追尾装置。 In a radio target tracking device that emits its own transmitted radio waves into the air, receives reflected radio waves from a target, and tracks the target, it consists of an antenna that emits radio waves, a transmitter that generates air radiated energy, and an antenna that receives radio waves. , a converter that converts the frequency of the target signal received by this antenna, and a receiver that amplifies the intermediate frequency converted by this converter,
An automatic gain adjustment circuit that controls the gain so that the receiver does not saturate due to excessive input compares and processes the target signal output voltage of the receiver with the control signal output voltage of the automatic gain adjustment circuit, and receives the signal at an arbitrary point. What is claimed is: 1. A radio target tracking device characterized by comprising means for changing the bandwidth of the device.
