Title:
不均一にサンプリングされる正弦波信号の検出、及びそれを利用するドップラセンサ
Document Type and Number:
Japanese Patent JP2010503871
Kind Code:
A
Abstract:
A Doppler sensor operates by transmitting pulses at non-uniform intervals. Samples reflected by an object are processed by multiplying each one by first and second coefficients c xk and s xk , the products being separately summed to form two measures which are examined to determine whether an object exhibiting a particular Doppler frequency f x has been detected. The samples occur at non-uniformly spaced times t xk such that the average of a cosine wave of frequency f x sampled at said times t xk would be substantially zero and the average of a sine wave of frequency f x sampled at said times t xk would be substantially zero
