An FM/CW radar system is disclosed for determining a safe stopping distance between a moving vehicle and a potential obstacle. The radar signal is modulated linearly over several slopes. A microstrip phased array transmit/receive antenna is also disclosed having a hybrid tap, corporate feed structur ...
In a cellular network, a GPS receiver includes circuitry that modulates a global positioning system (GPS) timing pulse signal with a carrier signal and transmits the modulated signal to one or more remote base stations. When the modulated timing pulse signal is received at a remote base station it i ...
In a radio access network (e.g., a cellular network), a radio receiver is configured with a switch that alternatively couples an antenna and an impedance-matched load to the remainder of the receiver. Sector load, e.g., rise-over-thermal (ROT), is monitored by comparing a first measurement of signal ...
