Phase association method of multisection sampled data
Jian Meng · Systems engineering and electronics · 2004
The characteristics of multisection sampled data are analysed by means of unit circle on complex plane firstly. On the basis of the analysis, two kinds of phase association methods of multisection sampled data are proposed for accumulating multidata in phase and improve the precision of frequency estimation. The new methods can be used in both detection of FMCW echo and frequency estimation of correlative pulse train. Finally, simulation data is given to certify the capability of new methods.
