摘要： A radar transceiver is provided. The radar transceiver includes an electrical balance duplexer that is coupled to a transmission node of a transmission path, a reception node of a reception path, and an antenna node and that is configured to isolate the transmission path from the reception path. The electrical balance duplexer includes a hybrid transformer network and a non-tunable balancing impedance. The non-tunable balancing impedance is configured to provide a fixed impedance value that corresponds to an impedance value at the antenna node.

摘要： A method for extracting spatial resolution and/or velocity resolution of a single-input single-output radar acquiring raw radar data with a frequency scanning antenna is provided. The method includes steering a radar beam with the aid of the frequency scanning antenna with respect to an area to be illuminated by the radar, and dividing the area into at least two angular sectors. In this context, the at least two angular sectors are configured in a manner that the at least two angular sectors overlap with respect to each other.

摘要： Systems and methods providing a wakeup receiver for latency-critical applications are described herein. An example system includes a wakeup receiver communicatively coupled to a communication channel. The wakeup receiver is configured to monitor an input signal of the communication channel and down-convert the input signal to a DC signal. The system also includes an analog to digital converter (ADC) configured to digitize the DC signal and provide an ADC output. The system further includes a digital baseband (DBB) module configured to determine a received signal strength indication (RSSI) from the signal. The DBB is also configured to, for each packet, determine a respective packet length and compare the RSSI and respective packet length with a two-dimensional template. The DBB is additionally configured to, based on the comparison, determine an interrupt condition and, based on determining the interrupt condition, generate a wakeup signal.
