6.1 Typical Radar Measurement Cycle

Figure 6-1 shows a typical radar application flow during one frame of operation.

Typical Radar Measurement Cycle For One Frame Figure 6-1 Typical Radar Measurement Cycle For One Frame

The different states during one frame of operation are shown in Table 6-1.

Table 6-1 Different States During Operation
State Description
Chirp

The period of time in which one or more transmitters emits/receives an FMCW wave.
Burst A sequence of chirps.
Frame

A time period that consists of a sequence of bursts followed by data processing. Frames are periodic on a defined interval.
Inter chirp idle The time period between chirps
Inter burst idle The time period between bursts
Inter frame idle

The time period between the end of one frame and the beginning of the next frame
Data processing

The time period in which the device processes the radar data collected in the previous frame
