Automatic Measurement System for RF Pulse Stability Parameters

摘要

This paper describes a new automatic system for measurement of transmitter stability parameters, esp. the frequency stability of RF pules series, which can limit the performance of variours coherent pulse radars. The practicability to characterize the stability of RF pulse series with interpulse variance in time domain and near-carrier phase noise in frequency domain is studied in the paper. The operation principle, system construction and calibration methods of quadrature dual channel frequency and phase discrimination system for the measurement of interpulse variance are discussed here. This system is effectively used in the measurement of stability of radar transmitters.
