Abstract
A cycle estimation device () includes: a candidate cycle extraction unit () which extracts a candidate cycle that is a cycle determination target from an input time-series pulse train; a pulse train shape analysis unit () which converts arrangement of the time-series pulse train into numerical values on the basis of the extracted candidate cycle and outputs a constant that adjusts a random noise threshold value of pulse repetition interval (PRI) conversion in response to an index indicating a degree of concentration of calculated numerical values; and a cycle detection unit () which executes PRI conversion using a value of the candidate cycle and the constant and performs cycle determination and cycle value detection.
