In deep space exploration, signal of very far-away spacecraft is usually highly dynamic and weak. During the operation of spacecraft maneuver, usually omnidirectional antenna with low power is adopted, which makes it difficult to achieve reliable telemetry reception and decoding. In this paper, we present a new method of monitoring the status of spacecraft maneuver with radiometric doppler tracking, the method only depends on the carrier without decoding telemetry signal. The basic theorem and algorithm are discussed in detail, and experiment demonstration could testify the effectiveness of the method presented in the paper.
