Abstract: Disclosed is a solid lithium-lead blanket for a fusion reactor, where a solid lithium-lead alloy is adopted as a neutron multiplier and a tritium breeder, and is placed in a form of a unitary or binary pebble bed inside a structural skeleton composed of structural materials; and nuclear thermal deposition in the solid lithium-lead alloy generated due to an interaction between the solid lithium-lead alloy and a fusion neutron is moved out by a coolant. A proportion of lead atoms in the solid lithium-lead alloy is low, so that, under normal operations and accident conditions of the blanket, the solid lithium-lead alloy always remains in a solid state without melting, and tritium can be brought out of the reactor by purge gas flowing through the pebble bed to allow tritium self-sufficiency. The blanket of the present disclosure does not require beryllium to meet the requirements of tritium breeding.

Abstract: A radar anti-spoofing system for an autonomous vehicle includes a plurality of radar sensors that generate a plurality of input detection points representing radio frequency (RF) signals reflected from objects and a controller in electronic communication with the plurality of radar sensors. The controller executes instructions to determine time-matched clusters that represent objects located in an environment surrounding the autonomous vehicle based on the input detection points from the plurality of radar sensors. The controller determines an adjusted signal to noise (SNR) measure for a specific time-matched cluster by dividing an SNR of the specific time-matched cluster by a range measurement of the specific time-matched cluster. The controller determines a velocity-ratio measure of the time-matched cluster by dividing a motion-based velocity by a Doppler-frequency velocity, and identifies the time-matched cluster as either a ghost object or a real object.
