Radar
Radar is an acronym1 for Radio Detection and Ranging2. In the simplest radar system, a radio transmitter produces a pulse of radio frequency energy a few microseconds long. This pulse is fed into a highly directional antenna3, where the resulting radio wave propagates away4 at the speed of light. Aircraft in the path of this wave will reflect a small portion of the energy back toward a receiving antenna, situated near the transmission site. The distance to the object is calculated from the time between the transmitted pulse and the received echo. The direction to the object is found more simply; you know where you pointed the directional antenna when the echo was received.
The operating range5 of a radar system is determined by two parameters: how much energy is in the initial pulse, and the noise level of the radio receiver. Unfortunately, increasing the energy in the pulse usually requires making the pulse longer. In turn, the longer pulse reduces the accuracy and precision of the time measurement. This results in6 a conflict between two important parameters: the ability to accurately determine an object's distance.
Digital Signal Processing (DSP) has revolutionized radar in three areas. First, DSP can compress the pulse after it is received, providing better distance determination without reducing the operating range. Second, DSP can filter the received signal to decrease the noise. This increases the range, without degrading the distance determination. Third, DSP enables the rapid selection and generation of different pulse shapes and lengths. Among other things, this allows the pulse to be optimized for a particular detection problem. Now the impressive part: much of this is done at a rate comparable to the radio frequency used, as high as several hundred megahertz! (1591p.s.)

I. Answer the question:
What is the basic principle of radar operation?
An aircraft propagates away the radio pulse.
The directional antenna produces the radio pulse.
The radio transmitter emits the radio pulse concentrated and sent away by the directional antenna.
The distance to the object is calculated by the frequency of the reflected wave.
