Results are presented in the form of worldwide plots of notional signal to noise ratio. The ladar and 95 GHz system types exhibit similar SNR performance for forward oblique clear air operation. 1.557 m ladar performs well for vertical geometries in the presence of ground fog, but has no ...
We analyze the signal-to-noise-ratio equations for a heterodyne laser radar with identical transmit and receive optics. We defines the beam-profile efficiency, a quantity that must be maximized to optimize a system design. This calculation can be used to evaluate a system in both near and far...
With poor NF, there is the possibility that targets may not be detected depending on the signal to noise ratio (SNR) required. A traditional communication system would typically target an SNR of 3 dB. For a radar system, this is not quite required, and typical minimum SNRs would be in th...
The signal-to-noise ratio (SNR) of the generated waveform was also calculated based on the PSD results (Methods), then compared with the signal generated by the AWG (Fig. 2c). The SNR results show no notable difference between these two signals across the 25-GHz bandwidth, proving that ...
Detection of objects using radar involves sophisticated signal processing. For a single pulse the following signal to noise ratio is: Observe that the received power drops with the fourth power of the range, so radar systems must cope with very large dynamic ranges in the receive signal processing...

当杂波统计量为高斯分布时,可以将杂波信号回波和噪声回波结合起来,由信杂波+噪声比(Signal-to-Clutter+Noise-Ratio)导出一个确定雷达测量精度的新值,用SIR表示 $$ SIR=\frac{1}{\frac{1}{SNR}+\frac{1}{SCR}} \tag{6.26} $$ 注意,SCR是通过将Eq.(6.24)除以Eq.(6.25)来计算的。 学习笔记 为了理解...
