Abstract:

The design of a new type of doppler simulator, fabricated at USAEL, is based on a rectangular waveguide in the form of a closed E-plane circular loop fed by a 90-degree H-plane corner. The waveguide loop is divided symmetrically in the plane of the loop. The two sections are so arranged that one, the rotor, may be continuously rotated while the other, the stator, which contains the input waveguide, remains fixed. The simulator produces a highspeed linear phase shift with relatively low mechanical rotational speed. Target direction, approaching or receding, can be simulated by choosing the appropriate direction of rotation. The device is useful in a laboratory bench setup as well as for field operation. Author
