As explained earlier, the longer the pulse, the worse the resolution would be. Range resolution is proportional to pulse width and inverse proportional to bandwidth Shorter pulse will improve range resolution but will also reduce the power of the transmitted radar wave, thus reduce radar detection ...
Radar - Reflection, Resolution, Range: The performance of a radar system can be judged by the following: (1) the maximum range at which it can see a target of a specified size, (2) the accuracy of its measurement of target location in range and angle, (3
更准确地说,搜索量(search volume)Ω(以立体度为单位in steradians)由\Omega = \frac{\theta_2 - \theta_1}{(57.296)^2} \times 360° \tag{1.100}因此,搜索量为\Omega =360 \times \frac{\theta_2 - \theta_1}{(57.296)^2} = 360 \times \frac{13.13-2.08}{(57.296)^2}=1.212 \ \ stera...

In addition to other factors including antenna size and spectral efficiency, high-frequency radars’ shorter wavelengths mean they can go through more cycles in a given period , contributing to a broader operating bandwidth. Radars that operate in this range are best known for fire contr...
the radar equation to the 1970 and 1990 editions of Skolnik’s Radar Handbook , but to this day other texts continue to use radar equations in which a “receiver bandwidth B” appears in the denominator of the equation to give receiver “noise power” that is proportional to that bandwidth....
Short pulses, however, require wide bandwidths in the receiver and transmitter (since bandwidth is equal to the reciprocal of the pulse width). A radar with a pulse width of one microsecond can measure the range to an accuracy of a few tens of metres or better. Some special radars can ...
The resolution of wideband coherent radar data can be improved in two ways. The first involves the use of state-of-the-art spectral analysis methods which improve resolution relative to conventional Fourier processing; these spectral methods employ bandwidth extrapolation of the signals in a radar fr...
A Frequency Divided Multiple Input Multiple Output (FD-MIMO) radar is proposed, which can synthesize the High Range Resolution Profile (HRRP) by transmitting and receiving narrowband waveforms in different frequency bands without over-demanding system bandwidth.And thanks to short pulse duration, the ...
This photonic radar can achieve millimetre-level range resolution based on synthesized radar signals with a bandwidth of up to 30 GHz. The high resolution of the radar system enables accurate respiratory detection from breathing simulators and a cane toad as a human proxy. Moreover, we ...
