Radar - Pulse, Detection, Reflection: The most common type of radar signal consists of a repetitive train of short-duration pulses. The figure shows a simple representation of a sine-wave pulse that might be generated by the transmitter of a medium-range
This paper examines various factors that effect the accuracy of radar measurement of ocean wave height from space, with particular emphasis on the effect of pulse width. It is shown that at a given signal-to-noise ratio, large or small, there is a pulse width that yield an optimal ...
Range resolution is the ability of a radar to separate two targets that are close together in range and are at approximately the same azimuth. The range resolution capability is determined by pulse width.A radar pulse in free space occupies a physical distance equal to the pulse width multiplied...

The pulse length is usually called Pulse Width in radar systems. These listening times represent one pulsed radar cycle time, normally called the interpulse period or (IPP) or pulse repetition interval (PRI). Pulsed Wave Radar typically operates at frequencies between 6 and 28 GHz. This form...
Because the initial pulse is time-reversed, the filtered output is delayed by the pulse width T, which is 1 second. To show this, time-reverse the original linear FM pulse and pad the pulse with zeros to make the pulse and transmitted waveform the same length. Calculate and plot the ...
pulse width is given in the figure as 1 microsecond (10−6second). It should be noted that the pulse is shown as containing only a few cycles of the sine wave; however, in a radar system having thevaluesindicated, there would be 1,000 cycles within the pulse. In the figure the ...
Pulsewidth versus required SNR for three different detection range values.img 在开发雷达模拟时,式(1.57)在以下意义上非常有用。雷达系统通常利用有限数量的脉冲宽度(波形)来完成所有指定的操作模式。其中一些波形用于搜索和检测,其他波形可用于跟踪,而有限数量的宽带波形可用于识别目的。在搜索操作模式中,例如...
Synthetic aperture radar (SAR) image formation. In SAR, the radar pulse width determines the illumination in the range direction, and the antenna beam width determines the illumination in the cross-range direction (see figure). When the antenna arrives at position 1 and partially illuminates the ...
