Resolution of range and velocity ambiguity for a medium pulse …

WebbThe ambiguity function is the two-dimensional (2-D) autocorrelation of waveform in time and frequency. It can be described as: (10.50) where X ( t, f) is the 2-D ambiguity function in time and frequency, and μ (τ) is the waveform described in the time domain. The diagram that represents the ambiguity function is called the ambiguity diagram. Webb• resolution of the radar display unit Range resolution as a distance can be calculated as follows: R res = c * τ /2 Where, τ is the transmitted pulse width and c is the velocity of light in the free space.

Webb30 okt. 2024 · The primary task of carrier phase positioning is ambiguity resolution (AR) with rapidity and reliability. As the pseudolite system is usually operated in the dense multipath environment, cycle slips may lead the conventional least-squares ambiguity decorrelation adjustment (LAMBDA) method to incorrect AR. Webb28 maj 2011 · Both range and Doppler measurements are ambiguous, but each will not be aliased or folded as severely as the more extreme low or high PRF modes. This can provide a good overall capability for detecting both range and moving targets. WebbWSR-88D Range-And-Velocity Ambiguity Mitigation Reports.
