AWR1243: Cascade : Change the maximum range

Alice Ruget

Part Number: AWR1243
Other Parts Discussed in Thread: MMWCAS-DSP-EVM, TIDEP-01012, TDA2

Hi, I am using the TI AWR1243P Cascade Radar evaluation board (TIDEP-01012) with the TI MMWCAS-DSP-EVM Evaluation module (TIDEP-01017).

I am trying to change the maximum range of my data. The estimator provided by mmwavestudio doesn't take into account my board, so I am trying to vary the parameters (slope etc .. ) in the configuration scripts.

However, I always find some issues: for example if I increase the slope with a ramp end time constant, then the maximum frequency is too large. If I then change the ramp end time with a number of ADC samples constant, the time is too short to take all the samples etc..

Is there a procedure to follow to change the parameters in the right order and to directly take into account everything?

Thank you!

All the best,
Alice

Hi,

Please see following faq that explains how the maximum range is computed.

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1050220/faq-computing-maximum-range-velocity-and-resolution-mmwave-system

After you understand which parameters impact the maximum range, you would need to modify the chirp configuration used

thank you

Hi,

Thank you. Could you give some guidelines/documentation on how to modify the chirp configuration?

There is a lot of parameters to take into account (sample frequency, ramp end time, maximum possible frequency etc), and I haven't find any possible configuration for a maximum range of 5m for example.

Have you tried the mmWave Sensing Estimator?

Thank you

Unfortunately, this sensing estimator is not configured for the AWR1243P Cascade Radar, which has 12 Tx and 16 Rx.

This is correct, it would still be helpful to understand how a chirp configuration is created. This does not change for the 12TX example.

I am attaching a chirp configuration that was used for 3Tx for short range. ods_aop_config.cfg

I hope this helps understanding how the configuration can created.

Unfortunately we don't have an out of the box 5m configuration available for cascade.

Thank you

Hi,
Thank you for your answer. I think I am missing a basic concept here. I thought the Cascade_Configuration_MIMO.lua given with the mmwavestudio package would do automatically the configuration of the chirp knowing the different parameters (slope, sample frequency etc etc.) Is is not the case? Do I have to manually configure the chirp as well?

I am putting below the Cascade_Configuration_MIMO.lua script. Could you confirm that this script is relevant for my radar device (AWR1243P Cascade Radar) and activate all the Rx antennas I have? The data I have acquired until now seems off : I have wrong range values and no angular resolution.

Yes,

Configuring the chirp means, configuring the slope..

This is done in the LUA script by providing the information below

Alice Ruget said:
-- Profile configuration

local profile_indx = 0

local start_freq = 77 -- GHz

local slope = 79 -- MHz/us

local idle_time = 5 -- us

local adc_start_time = 6 -- us

local adc_samples = 256 -- Number of samples per chirp

local ramp_end_time = 40 -- us
