Doppler radar
First Claim
1. Doppler radar for measuring objects, comprising a first and a second substantially prismatic cavity resonator each having sides, each having an end facing the object to be measured and each having substantially equal dimensions, a common wall connecting a respective side of each of said cavity resonators to each other, an oscillator diode disposed in said first cavity resonator, a receiving diode disposed in said second cavity resonator, said end of said first cavity resonator facing the object to be measured being closed and said end of said second cavity resonator facing the object to be measured being open, said common connecting wall having an opening formed therein, said first cavity resonator having another end opposite to said end facing the object, and said opening being spaced from said other end by a distance of (2n+1).λ
- /4, where λ
is the wavelength of oscillations excited in said first cavity resonator and n is an integral number starting from 0.
