Polar vs. Cartesian Coordinates Convert between Cartesian and Polar coordinates. In the Cartesian system the coordinates are perpendicular to one another with the same unit length on both axes. Cartesian coordinates in the figure below: (2,3) A Polar coordinate system is determined by a fixed ...

Points of given φ lie on a half-plane which extends from the polar axis to infinity in the direction given by φ. In order for coordinate sets and arbitrary spatial points to be unambiguously related, we need to restrict the range of r to 0≤r<∞, with θ in the range 0≤θ≤π ...
The nut 14 thus moves the stylus 13 over the chart 5 according to the polar range R. The signalling elements 36, 38 of the trainer are driven from the azimuth and range elements 5, 14 respectively. Hunting of the servos may be prevented by velocity feed-back. The primary and secondary...

The end of this line segment is reached by moving perpendicularly to the x-y plane from the point P. This point is called the projection of the point P into the x-y plane. The three spherical polar coordinates are r, θ, and ϕ. The coordinate r is the distance from the origin ...
Using the Frenet frame, the components of the velocity and acceleration along the frame unit vectors are calculated. Numerical simulations are performed for two different configurations in order to validate the approach.doi:10.1002/cmm4.1049Mihai Dupac...
This article compares a Scale Unscented Transform H-infinity filter (SUT - H-infinity) and UKF for the bearings-only tracking problem in Modified Polar Coordinates (MPC) and Cartesian coordinates (CC). Its objective is to track the kinematics (position, velocity) of a moving target us...
