CIRCULARLY POLARIZED AUTOMOTIVE RADAR FOR IMPROVED SIGNAL TO NOISE RATIOA sensor assembly for detecting an object is disclosed. The sensor assembly includes at least one radar transmitter configured to emit transmitted radar waves having a first polarization. The sensor assembly also includes at least ...
Most modern radars use some form of pulse compression to improve the range resolution and signal-to-noise ratio (SNR). As a result, maintaining the integrity of the transmitted pulse through the signal chain is crucial. Pulse compression schemes allow radars to distingu...
to-noise ratio (SNR) for several application scenarios. In all the cases we examine we find that squeezed light offers no advantages for laser radar. 2 Signal-to-noise ratio From Helstrom(1976), Ch. IV, “Quantum Hypothesis Testing:” “Suppose that when the signal is present, it is...
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 ...

This technique reduces the signal-to-noise ratio and, as a result, the probability of target detection is degraded. On the other hand, deceptive jamming makes victim radar “think” there are false targets. The victim radar loses the ability to track real targets and, ...
The right side of the figure shows the bird's-eye plot, which presents a top down perspective of the scenario. All of the vehicles, detections, and tracks are shown in the coordinate reference frame of the ego vehicle. The estimated signal-to-noise ratio (SNR) for each radar measurement ...

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...
