Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/009356
Kind Code:
A1
Abstract:
A radar device (10) comprises a beat signal generation unit (30), a first signal processing unit (40), a second signal processing unit (50), and a speed determination unit (60). The first signal processing unit (40) observes a beat signal for a first number of observations during a first observation period, and calculates a first speed from the time sequence of the beat signal of the first number of observations. The second signal processing unit (50) observes the beat signal for a second number of observations during a second observation period and calculates a second speed from the time sequence of the beat signal of the second number of observations. The second observation period is longer than the first observation period. A time ratio is the ratio of the second observation period to the first observation period, and the second number of observations is a smaller number than the number obtained by multiplying the first number of observations by the time ratio.
