WebOct 1, 1973 · It is shown that, for Rayleigh‐angle incidence, reflection takes place into a cone rather than only into the forward direction. The apex angle of the cone is found to be twice the Rayleigh angle. WebDec 27, 2016 · The transmitted frequency is 5 MHz and the Doppler angle θ is 0 degrees. FIGURE 5-4. Doppler shift frequency from reflectors moving at a velocity of 50 cm/s versus Doppler angle. The transmit frequency is 5 MHz. The Doppler shift frequency is 3.2 kHz at 0 degrees, 2.8 Hz at 30 degrees, and 1.6 kHz at 60 degrees. WebThe Rayleigh criterion stated in the equation θ = 1.22 λ/D gives the smallest possible angle θ between point sources, or the best obtainable resolution. Once this angle is found, the distance between stars can be calculated, since we are given how far away they are.
