A radar device having a target search or tracking function includes a transmitting and receiving antenna that emits transmitted radio waves to the outside and receives reflected waves from the target, a transmitter unit that creates high-frequency power pulses, and radio waves from the transmitter unit. a transmission/reception switching unit that performs switching between transmitting and receiving the received radio waves from the antenna; a frequency mixer that converts the received radio waves input from the transmission/reception switching unit into an intermediate frequency; a local signal generation section that creates a local signal for conversion into a local signal, a receiver section that amplifies the frequency mixer output and then outputs it as a video signal, and a receiver section that receives the output of the receiver section and performs distance tracking, angle tracking, and detection. A signal processing section that processes and creates various triggers takes as input the video signal output from the receiver section and the predicted target position output from the signal processing section, divides the radar coverage area into small areas, and calculates the target altitude for each small area. What is claimed is: 1. A radar device comprising: a hit counting section that determines tracking quality for each hit; and a display section that receives and displays the outputs of the signal processing section and the hit counting section.
