Abstract:
1. A short range radar comprising: a transmitter section which radiates a short range wave to a space; a receiver section having a detector circuit composed of a branch circuit which receives a reflection wave of the short range wave radiated to the space by means of the transmitter section and branches in phase a signal of the reflection wave into first and second signals, a linear multiplier which linearly multiplies the first and second signals branched in phase by means of the branch circuit, and a low pass filter which samples a baseband component from an output signal from the linear multiplier; a signal processor section which carries out an analyzing process of an object which exists in the space based on an output from the receiver section; and a control section which makes a predetermined control with respect to at least one of the transmitter section and the receiver section based on an analysis result from the signal processor section.
