Claim 0:
1. A system for determining subsurface soil layer characteristics during the performance of an agricultural operation, the system comprising:
an agricultural machine configured to perform an agricultural operation on a field across which the agricultural machine is traveling;
a RADAR sensor provided in operative association with the agricultural machine, the RADAR sensor configured to capture RADAR data indicative of at least one of a presence of a compaction layer within the field, a location of the compaction layer within the field, or a seedbed depth within the field; and
a controller communicatively coupled to the RADAR sensor, wherein the controller:
receives the RADAR data from the RADAR sensor;
receives first input associated with a soil moisture content of the field;
determines a soil moisture content value for the field based on the received first input;
receives a second input associated with a soil oxygen content of the field;
determines a soil oxygen content value for the field based on the received second input;
determines a correction factor for the RADAR data based on the determined soil moisture content value and the determined soil oxygen content value;
adjusts the received RADAR data based on the determined correction factor to calibrate the RADAR data; and
determines the at least one of the presence of the compaction layer within the field, the location of the compaction layer within the field, or the seedbed depth within the field based on the calibrated RADAR data.
