Other Parts Discussed in Thread: AWR1642
Tool/software: Code Composer Studio
hello
we use the IWR1642 in MMW detection,our cherp period is 60 us and there is 64 chirps in a frame,
we ues one transmit antenna and four receive antennas for angle detection,so the phase information is very important.
the every signal of 64 the chirps should have the same initial phase, BUT we test several times, the phase is different.
In 3.6ms (60us * 64),the phase has changed 2 degree,and continuous change with the temperature raise.
As mentioned in the detasheet of IWR1642, these is a temperature sensor in BSS,and there is self-calibrating System Across Frequency and Temperature.
My questions are:
1.How is the temperature calibration works?
2.Is there any API for us to get the information of temperature sensor?
3.what is the phase precision in different chirps?
