Other Parts Discussed in Thread: IWR1843, TIDEP-0091
We are currently looking into the IWR1443 and IWR1843 series 76-81GHz mmWave Radar ICs primarily for tank liquid level sensing and possible solids as well. In reading through some of the documentation the IRW1443 includes MCU, hardware FFT accelerator, 512K memory, with 4 receivers and 3 transmitters and is very power efficient and can be optimized to run on 4-20ma loop power. The IWR1843 includes MCU, hardware FFT accelerator, 2M memory, 4 receivers, 3 transmitters, and DSP. The power optimization of the IWR1443 is a preferred option however accuracy will be critical as well. Would you be able to provide additional information related to how the performance of the IWR1443 and IWR1843 would compare in accuracy (mm) and distance (max distance) in low dielectric fluids such as oil and higher dielectrics for given range? Level detection in foam and or foam detection? Use of Closed-loop frequency synthesis (PLL) with chirp stitching (two ramps starting at different frequencies without any additional error over a single ramp) and zoom-FFT to minimize signal to noise ratio and enhance resolution? Are there any patent restricts relative to using the TI mmWave IC’s? Certification requirements?
Do you have any recommendations for which part may provide the best overall performance for liquid measurement? Also please specify all necessary demo boards, parts, software/hardware tools, programmer, IDE, evaluation GUI, etc needed to run a fluid level sensing evaluation.
I apologize for all the questions just looking to get a good perspective on what you have to offer.
