Claims

[Scope of utility model registration request]

A radar device that searches for or tracks a target includes a transmitting and receiving antenna that receives received radio waves or transmits transmitted radio waves, a transmitter that generates high-frequency power pulses, a receiver that receives received waves from the antenna, and a received signal. What is claimed is: 1. A tracking radar device that receives a signal converted from analog to digital as input, and is equipped with a main tracking gate circuit used when tracking a target, and a gate switching timing circuit used to switch gate width.
