The paper presents the new design of quadrature phase-sensitive detectors for amplitude and analogue channels of low-altitude surveillance radar. The main parameters of the quadrature phase detector, such as the sensitivity, dynamic range, and square phase between quadrature channels, are precisely measured in the laboratory. The quadrature components of the detector are gained to sufficient amplitude before to be delivered to binary or 11-bit quantum sets. These detectors are also fully compatible with control commands in different modes of the low-altitude surveillance radar.
