The invention belongs to the technical field of ice prevention and removal, and relates to an ultrasonic icing detection circuit. The system comprises a DSP, a transmitting circuit, a transmit-receive isolation circuit, a receiving circuit, a power supply module and a bus output. The transmitting circuit is composed of an excitation circuit and a tuning matching circuit. The receiving circuit is composed of a pre-amplification circuit, a high-speed ADC, a clock control circuit and a high-speed storage circuit. Compared with a common icing detection device which extends out of the surface of the airplane, the ultrasonic icing detection part which is flush with the surface of the airplane has the advantages that the adaptability to various different airplane types and environments is improved, the aerodynamic configuration of the airplane is not influenced, and the performance of the airplane is also ensured; the ultrasonic icing detection control part is installed in the airplane and is less affected by the external environment of the airplane. Aiming at an aircraft which develops rapidly at present, the device has the characteristic capability which is not possessed by a common icing detection device, and meets the requirements of a new-generation aircraft.
