Radar detection method and apparatus
View Patent ↗A radar system and method use a radar FMCW chirp having variable chirp characteristics.
1. An FMCW radar system, comprising:
a radar chirp signal generator to generate a plurality radar chirp signals, each one of the radar chirp signals having a respective start frequency and a respective end frequency, each one of the radar chirp signals in a respective time window, and each one of the radar chirp signals starting at a respective time offset within the respective time window, wherein at least one of the radar chirp signals has at least one of a different time offset than other ones of the radar chirp signals and a different start frequency than other ones of the radar chirp signals.
2. The system of claim 1 , wherein each one of the radar chirp signals has a respective randomly selected time offset.
3. The system of claim 1 , wherein each one of the radar chirp signals has a respective randomly selected start frequency.
4. The system of claim 1 , wherein the radar chirp signal generator is adapted for use in an automobile side object detection radar system.
5. A method of radar detection, comprising:
generating a plurality of radar chirp signals, each one of the radar chirp signals having a respective start frequency and a respective end frequency, each one of the radar chirp signals in a respective time window, and each one of the radar chirp signals starting at a respective time offset within the respective time window, wherein at least one of the radar chirp signals has at least one of a different time offset than other ones of the radar chirp signals and a different start frequency than other ones of the radar chirp signals.
6. The method of claim 5 , wherein each one of the radar chirp signals has a respective randomly selected time offset.
7. The method of claim 5 , wherein each one of the radar chirp signals has a respective randomly selected start frequency.
8. The method of claim 5 , wherein the radar chirp signal generator is adapted for use in an automobile side object detection radar system.
