Adaptive sync control in radar level sensors

An apparatus comprising:

• a controller configured to control first and second signal generators of a level sensor;
• wherein the controller is also configured to:
• determine whether the signal generators are able to generate first and second timing signals so that a timing difference between the timing signals obtains a target value while a control value in a control loop of the level sensor is within defined margins;
• in response to determining that the signal generators are not able to generate the timing signals so that the timing difference obtains the target value while the control value is within the defined margins, modify the target value;
• and
• determine whether the signal generators are able to generate the timing signals so that the timing difference obtains the modified target value while the control value is within the defined margins.

A system comprising:

• a transceiver configured to transmit signals toward material in a tank and to receive reflected signals from the material in the tank;
• a controller configured to generate measurements for the material in the tank based on the reflected signals;
• first and second signal generators configured to generate first and second timing signals for the transceiver;
• and
• a detector configured to generate a sync signal identifying a timing difference between the timing signals;
• wherein the controller is further configured to:
• use the sync signal to determine whether the signal generators are able to generate the timing signals so that the timing difference obtains a target value while a control value in a control loop is within defined margins;
• in response to determining that the signal generators are not able to generate the timing signals so that the timing difference obtains the target value while the control value is within the defined margins, modify the target value;
• and
• determine whether the signal generators are able to generate the timing signals so that the timing difference obtains the modified target value while the control value is within the defined margins.

A non-transitory computer readable medium containing instructions that, when executed by one or more processing devices, cause the one or more processing devices to:

• determine whether signal generators are able to generate first and second timing signals for a level sensor so that a timing difference between the timing signals obtains a target value while a control value in a control loop of the level sensor is within defined margins;
• in response to determining that the signal generators are not able to generate the timing signals so that the timing difference obtains the target value while the control value is within the defined margins, modify the target value;
• and
• determine whether the signal generators are able to generate the timing signals so that the timing difference obtains the modified target value while the control value is within the defined margins.
