First question asked Welcome!

Hello, I have a few questions about the pulse-mode used for the BGT60LTR11AIP. 

1. Is the pulse a chirp or does it have constant frequency? I see that I can set the center frequency but it isn't clear to me what the frequency range is once I set the center frequency.

2. Is there a way to extract samples per pulse? For example, using frame information? 

3. Is there a way to get the transmitted signal? Is the received signal already filtered when it is returned, removing information about the transmit signal?

 

Thanks!

Karly

Hello @karly_reimel ,

  1. BGT60LTR11AIP is doppler radar sensor, and a doppler radar is also called continuous wave (CW) radar, which    emits a single frequency at a time. The operating frequency range is between 61 GHz to 61.5 GHz (refer to datasheet)

  2. You can extract raw data by using the recording function of Radar Fusion GUI and also the Radar SDK has the app for raw data extraction from BGT60LTR11AIP (located at: \radar_sdk\apps\c\raw_data)

  3. The block diagram below gives the detailed connections between the blocks, the chip features a low-noise quadrature receiver stage. The receiver uses a Low Noise Amplifier (LNA) in front of a quadrature homodyne down-conversion mixer, where is the signal is derived from the internal VCO signal, an RC Poly-Phase Filter (PPF) generates quadrature LO signals for the quadrature mixer. The Analog Base Band (ABB) unit consists of an integrated sample and hold circuit for low-power duty-cycled operation followed by an externally configurable high-pass filter, a Variable Gain Amplifier (VGA) stage and a lowpass filter, which provides the output of IF signals which contains information about the target motion.
