41. Radar - Speed measurement • Speed is the change in distance to an object with respect to time. Thus the existing system for measuring distance, combined with a memory capacity to see where the target last was, is enough to measure speed. At one time the memory consisted of a user making grease pencil marks on the radar screen and then calculating the speed using a slide rule. Modern radar systems perform the equivalent operation faster and more accurately using computers. https://store.theartofservice.com/the-measurement-toolkit.html

42. Radar - Speed measurement • If the transmitter's output is coherent (phase synchronized), there is another effect that can be used to make almost instant speed measurements (no memory is required), known as the Doppler effect https://store.theartofservice.com/the-measurement-toolkit.html

43. Radar - Speed measurement • It is possible to make a doppler radar without any pulsing, known as a continuous-wave radar (CW radar), by sending out a very pure signal of a known frequency. CW radar is ideal for determining the radial component of a target's velocity. CW radar is typically used by traffic enforcement to measure vehicle speed quickly and accurately where range is not important. https://store.theartofservice.com/the-measurement-toolkit.html

44. Radar - Speed measurement • When using a pulsed radar, the variation between the phase of successive returns gives the distance the target has moved between pulses, and thus its speed can be calculated. Other mathematical developments in radar signal processing include time-frequency analysis (Weyl Heisenberg or wavelet), as well as the chirplet transform which makes use of the change of frequency of returns from moving targets ("chirp"). https://store.theartofservice.com/the-measurement-toolkit.html

46. Experimental psychology - Scales of measurement • Measurement can be defined as "the assignment of numerals to objects or events according to rules." Almost all psychological experiments involve some sort of measurement, if only to determine the reliability and validity of results, and of course measurement is essential if results are to be relevant to quantitative theories. https://store.theartofservice.com/the-measurement-toolkit.html

47. Experimental psychology - Scales of measurement • The rule for assigning numbers to a property of an object or event is called a "scale". Following are the basic scales used in psychological measurement. https://store.theartofservice.com/the-measurement-toolkit.html

48. Experimental psychology - Nominal measurement • In a nominal scale, numbers are used simply as labels – a letter or name would do as well. Examples are the numbers on the shirts of football or baseball players. The labels are more useful if the same label can be given to more than one thing, meaning that the things are equal in some way, and can be classified together. https://store.theartofservice.com/the-measurement-toolkit.html

49. Experimental psychology - Ordinal measurement • An ordinal scale arises from the ordering or ranking objects, so that A is greater than B, B is greater than C, and so on https://store.theartofservice.com/the-measurement-toolkit.html
