A Moving Single Station Passive Ranging Method by Interchangeable Relationship Between Frequency Shift and Path Difference
Tao YU
Abstract
Based on the mathematical definition of Doppler shift equation, the commutative relation between Doppler shift and path difference can be obtained by using the difference of distance. By using the basic trigonometric function, a passive ranging solution based only on two consecutive Doppler frequency shift measurement can be obtained. Compared with the existing ranging solution obtained by frequency shift difference based on mathematical definition of Doppler rate of change, the new ranging solution still keeps the simple mathematical expression and has better calculation accuracy. However, by comparison, it can be found that: under the same measurement method, although the mathematical expression of the ranging solution is different, the ranging error still remains the same magnitude. At the same time, it is found that the moving single-station Doppler frequency shift ranging has three characteristics: frequency shift exchange, mean effect, and result lag.
