2.1 Product features
SP25 is a lightweight and compact radar sensor in the same industry, which utilizes radar wave
to efficiently measure the distance and velocity of targets.
It has the lowest power consumption(0.5W) in the same industry, the smallest
volume(40mm*31mm*6mm), a distance-measurement of 30m and the advantages of advanced
performances, high cost efficient and integrated peripheral interfaces. And now it has been one
of the best 24GHz radar sensors, and has set up a new standard in obstacle avoidance and range
measurement.

UART interface default rate of Board-level communications is 115200bit / s, and the target
refresh rate of 50Hz. With universal external interface, you can quickly integrate with the host
computer or other MCU, which saves the user's configuration time.
2.2 Product specifications
SP25 is a K-band millimeter wave radar
sensor system, using a higher complexity
of the FMCW modulation mode. It can
detect the distance and velocity of
moving objects, and has a high range and
velocity measurement accuracy.
SP25 adopts one-way transmitting antenna and one-way
receiving antenna, and the transmitting and receiving antenna is
separated. Therefore, the radar transmitting and receiving link
has a
higher isolation. Besides, the radio frequency MMIC is
coplanar with the antenna, which can reduce the loss of radio
frequency link. The low side lobe synthesis of the antenna
pattern
by using Taylor algorithm has a better suppression ratio than
that of
-15dB side lobe, which makes that SP25 is not susceptible to the interference of ground moving
targets, and can improve the radar detection performance.
Product specifications are as the following table 1.
