laser-doppler radar is more accurate than microwave radar microwave radar may not ensure absolute precision in measuring varying speeds the light-beam radar can measure only slow speeds with accuracy microwave radar operates at a higher frequency than laser-doppler radar
it is one thousand times more precise than microwave radar it provides precise measures of the velocity of space vehicles it is a new system of radar it can measure the movement of a spaceship less accurately than a microwave radar
even in clear weather radar should be used radar should be used only in clear weather when approaching a very large ship or a tow or when approaching a ship at close rangeradar should not be used in modern times, radar has little use for navigation
