Abstract
A continuous signal of a radio frequency source is connected to an antenna using at least one mixer to generate and analyze radar pulses. To generate a radar pulse, the at least one mixer is briefly placed into a state of low throughput loss. After the radar pulse is generated and transmitted, the at least one mixer is switched over to a receive mode to analyze a mixed signal formed by a receive signal, in particular at least one radar pulse reflected by an object, and the continuous signal of the radio frequency source.
Claims20
A method of generating and analyzing a radar pulse, the method comprising:
- connecting a continuous signal of a radio frequency source to an antenna via at least one mixer;
- generating the radar pulse by placing the at least one mixer briefly into a state of low throughput loss;
- transmitting the radar pulse;
- and
- after the radar pulse is generated and transmitted, switching the at least one mixer to a receive mode in order to analyze a mixed signal that a receive signal forms with the continuous signal of the radio frequency source.
A radar sensor for generating and analyzing a radar pulse, comprising:
- an antenna;
- at least one mixer;
- a radio frequency source connected to the antenna via the at least one mixer;
- a device for briefly placing the at least one mixer into a state of low throughput loss for generation of the radar pulse;
- a device for switching the at least one mixer into a receive mode;
- and
- an analysis unit configured to analyze a mixed output signal that a signal of the radio frequency source forms with a receive signal.
