METHOD FOR DETERMINING THE DISTANCE TO REAL with the source of radiation signals with different frequencies

摘要

1. A method for determining the range to the object with the radiation source signals with different frequencies, comprising the simultaneous reception of at least two signals with different frequencies and subsequently measuring the phase of the received signals relative to the reference signal generator with passive measurements of phase method, characterized in that the conversion is carried out measured values phase of each signal to a digital value of the time interval between the reference oscillator signal and the received signal with passive measurements method or times Nogo interval between transmitted and received signal at a radar, based on the use of the phase measurement method, and the distance is calculated using an adaptive formula, the number of units which is one more than the value of the absolute difference between modules comparisons: where x - reduced range value disclosure ambiguous measurements; bs - image-residues (interpreted as values ​​proportional to the measured phase values, such as values ​​of residues corresponding to the measured phase value, y sheath on the proper wavelength λs, s = 1,2; ms - comparison modules, which are understood to wavelengths received signal λs, s = 1,2; Δb = (b1-b2) - difference images residues bs, which is interpreted in accordance with the selected mathematical model as a phase difference Δφ = (φ1-φ2) (this model allows for more accurate range measurements current practice phase method, when a difference frequency in addition to the combined scaled frequency to resolve the ambiguity and allows use without difficulty in practice Radiotekhn iCal mate measurements
