LA JOLLA, Calif. (KGTV) - Researchers at UC San Diego have found a way to improve radar technology that can make self-driving cars safer."Our vision is to make self-driving cars much more safer than how we humans drive," says Dinesh Bharadia, an Assistant Professor of Electrical and Computer Engineering at UC San Diego.Bharadia led a team of researchers working on ways to help autonomous vehicles see in bad weather.Currently, he says, self-driving cars rely on LiDAR, a light-based radar system. But it's performance is limited because it uses a low frequency that reflects in bad weather.Bharadia says his team tested wireless radar, which has a higher frequency wavelength and found it can rain and fog.However, the wireless radar's sight range is limited. So Bharadia's team built a system where five wireless radars work together to create a more full "view" of the road."From each radar's vantage point, you see something different," says Bharadia. "Those different things, observed from five different radars, gives you much more detailed aspect ratio of another car (on the road)."Bharadia says the combination of all five radars helps create a 3-D image of other objects on the road. That helps the car's self-driving system figure out how to avoid them."You need to know the exact aspect ratio of the other cars on the road," he says. "Only then can you drive around them if you need to."Bharadia says carmakers like Toyota and Honda have been helping with the research and development. He thinks this new technology could be on the road within 2-3 years."Radars are already out there," he says. "We just need to plug in our software to make the cars more autonomous..."It's a simple technology that can be widely deployed and used to make our roads safer for everyone."Bharadia and his team will present their findings at the Sensys Conference this week.

LA MESA, Calif. (KGTV) – After being closed by the city in March due to the coronavirus pandemic, the La Mesa attraction known as the “secret stairs” was reopened to the public.The city announced Wednesday that the popular destination near Windsor Drive is open with specific social distancing guidelines in place.The stairs, widely used as a community trail or exercise route, was shut down on March 24 due to visitors not following social distancing rules.Despite the closure, some residents told the city that warning signs noting guidelines were being ignored.With the reopening, city officials are asking visitors to know the following before going to the stairs:WEAR A MASK: Everyone should wear a mask covering their face at all times while in this public space.MAINTAIN DISTANCE: Keep physical distance of 6 feet between individuals from different households and prevent crowding.PLAN AHEAD: Visit at times or days that are less crowded.KNOW WHEN TO STAY HOME: Those with underlying medical conditions should avoid public spaces when others are present. Stay home if you are feeling sick.SHARE OUR SPACE: To avoid crowding and allow everyone to use this space, please limit your time. Do not gather at entrances or near neighbors’ homes. Please no groups or fitness classes.The city is urging visitors to follow the rules “to help ensure these stairs can remain open for use.”Visitors are also asked to “be respectful of neighbors by keeping noise levels down.” 1477
