<p>and <a href="page.php?w=Decca_Navigator_System">Decca</a> mentioned at earlier (recall the same math works for moving receiver and multiple known transmitters), use spacing larger than 1 wavelength and include equipment, such as a <a href="page.php?w=phase_detector">phase detector</a>, to count the number of cycles that pass by as the emitter moves. This only works for continuous, narrow-band waveforms because of the relation between phase , frequency  and time :<br/>
: The phase detector will see variations in frequency as measured <a href="page.php?w=phase_noise">phase noise</a>,</p><p>
