Claims

[Scope of utility model registration request]

An RF amplifier that amplifies the reflected signal from the target with low noise, a mixer that converts this output signal into an IF signal, an IF amplifier that amplifies the output signal of this mixer, and an IF amplifier that inputs the output signal of this IF amplifier. A power divider for distributing output signals, an IF amplifier for amplifying one output signal of this power divider, a correlator for correlating the output signal of this IF amplifier, and a correlator for amplifying the output signal of this correlator and An IF amplifier that sends a signal to a subsequent stage of the receiver, an IF amplifier that amplifies another output signal of the power divider, a correlator that correlates the output signal of this IF amplifier, and amplifies the output signal of this correlator. an IF amplifier that sends the output signal to the downstream stage of the receiver, an IF amplifier that amplifies the other output signal of the power divider, a correlator that correlates the output signal of this IF amplifier, and an output of this correlator. A radar receiver comprising an IF amplifier that amplifies a signal and sends the output signal to a subsequent stage of the receiver.
