Transitioning from 24 GHz to 79 GHz delivers 20x better performance in range resolution
The IWRAP is a downward-pointing, conically-scanning, dual-frequency (C- and Ku-band), dual-polarization, dual-beam airborne radar that measures surface backscatter and volume reflectivity/Doppler velocity from precipitation at 30-m range resolution
. The IWRAP scans at 60 revolutions per minute, allowing wind retrievals with ~200-m horizontal and ~30-m vertical grid spacing.
mmWave radar sensors provide smart, highly accurate stand-alone sensing with less than a 4-centimeter range resolution
, range accuracy down to less than 50 micrometers and range up to 300 meters.
Under the condition of the LFM bandwidth = 80 MHz, the theoretical range resolution
attains 1.86 m.
Since automotive requirements are gradually increasing, automotive radar needs improved range resolution
and maximum distance.
The abovementioned approaches have intrinsic limitations in terms of range resolution
, endurance, and costs.
To improve the data rate and range resolution
, OFDM linear frequency modulation (LFM) signals based on fractional Fourier transform (FRFT)  and a random stepped-frequency (SF) OFDM signal based on correlation processing  have been given.
It is well known that the range resolution
limit with far-zone measurements is given by 
The related parameters descriptions of the radar data are listed as follows: the carrier frequency is 10 GHz with signal bandwidth of 400 MHz, a range resolution
is 0.375 m.
The Kodak SONORA NEWS plate has impressive quality (3-97 percent dot range resolution
at 150 lines per inch, depending on the capability of the imaging device), a strong print performance, including 200,000 impressions run length capability for web presses, and a full range of gauges including 0.40 mm thickness and very large format (VLF) size capability.
ABSTRACT: In this paper multi carrier radar signals have been introduced to achieve high range resolution
in radar systems by controlling the large peak to mean envelope power ratio and large power fluctuations that is sensitive to non-linearities in the system due to power amplifier.
