WebThe Space Department needed to develop several novel antennas to radiate the Doppler signal to the ground. The first Transits used an APL-invented spherical projection of a logarithmic spiral (Fig. 3). When later spacecraft departed from spherical shape, the design switched to the aptly-named "lamp shade" antenna.

WebNov 6, 2024 · See here for an example of how to compute spherical harmonics on the 2D grid (theta, phi), and plot the results as a nice surface in 3D. By the way, you will want to compute the surface values over the full range of angle [0,pi] and [0,2*pi], so that your surface does not have a hole at the south pole or a gap along the prime meridian. WebMay 11, 2024 · NB: In the following I am using the so called mathematics convention for spherical coordinates, i.e x = rcosθsinϕ, etc. There are two relevent formulae you'll need to compute the tensor Laplacian.
