What is claimed is: 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.
