Research was continued on the evaluation and improvement of coherent radar beacons and a study was made of the use of tunnel diodes, varactor diodes and other solid state devices for use in beacons. Novel tunnel-diode amplifier circuits were introduced for stable operation. Stability criteria were established by which these amplifier circuits can be made unconditionally stable. The operation of the Doppler tracking loop of a coherent radar was investigated with regards to two indices of performance 1 low-deviation and 2 low rateof-change of the input frequency modulation. Of particular interest is the case where the f-m modulation arises from rotation of the missile antenna. Author
