1. A method for partitioning a radar acquisition volume, the method comprising the steps of: determining, using a radar beam control, an allocated time to search an unpartitioned volume;determining a number of beam rows in an unpartitioned acquisition face;determining an average per-row search time for searching an angular region based on the determined allocated time and determined number of beam rows in an unpartitioned acquisition face;determining a number of beam rows in an allotted acquisition period that is searchable based on the average per-row search time;calculating a maximum elevation extent based on the number of beam rows in the allotted acquisition; andsearching, by an antenna face controlled by the radar beam control, an angular extent of the search volume based on the calculated maximum extent. 2. The method of claim 1, wherein the calculation of the maximum elevation extent is performed using the radar beam control and comprises determining an average search time of each row of the beams in the allotted acquisition period. 3. The method of claim 1, wherein the calculation of the number of beam rows in the allotted acquisition period is based on the condition that a total time to search the number of beam rows in an unpartitioned acquisition face is less than a maximum allowable search time. 4. The method of claim 1, wherein the calculation of the number of beam rows in the allotted acquisition period is based on a condition that the number of beam rows in the allotted acquisition period is expanded to at least one outer row. 5. The method of claim 1, wherein the calculation of the maximum elevation extent comprises adding an elevation pad to an extent sent. 6. A method for calculating, using a radar beam control, a maximum extent in an allotted acquisition period that is used to partition a search volume of an angular region of a radar acquisition volume, the method comprising the steps of: determining, using the radar beam control, an average search time of each row of beams, wherein the determined average search time is based on a number of beam rows in an unpartitioned acquisition face;calculating a number of beam rows in the allotted acquisition period that is searchable in the allotted acquisition period based on the determined average search time; andestimating a maximum elevation extent that is searchable by the number of beam rows in the allotted acquisition period. 7. The method of claim 6, further comprising adding an elevation pad to an extent sent. 8. The method of claim 6, wherein the calculation of the number of beam rows in the allotted acquisition period is based on the condition that a total time to search the number of beam rows is less than a maximum allowable search time. 9. The method of claim 6, wherein the calculation of the number of beam rows in the allotted acquisition period is based on the condition that the number of beam rows in the allotted acquisition period is expanded to at least one outer row. 10. A system for partitioning a radar acquisition volume comprising: a command and decision unit that determines an azimuth and elevation extent of a search volume about a cue direction and angular extents of beams in azimuth and elevation based on defined bandwidths of the beams; anda radar beam control that is electrically coupled to the command and decision unit, wherein the radar beam control includes the following operations: from the angular extents in azimuth and elevation for each beam, determine a number of beams required to cover a search face,determine a maximum allowable search time for searching the angular region,determine a search time based on the determined number of beams,compare the search time with the maximum allowable search time,if the search time is greater than the maximum allowable search time, determine a maximum search elevation that is used as an allotted acquisition period,determine an allocated time to search an unpartitioned volume,determine a number of beams rows in an unpartitioned acquisition face,determine an average per-row search time for searching the angular region based on the determined allocated time and determined number of beam rows in an unpartitioned acquisition face,determine a number of beam rows in an allotted acquisition period that is searchable based on the average per-row search time,calculate a maximum elevation extent based on the number of beam rows in the allotted acquisition period, andsearch a full angular extent of the search volume based on the calculated maximum extent. 11. The system of claim 10, wherein the radar beam control determines an average search time of each row of the beams. 12. The system of claim 10, wherein the radar beam control calculates of the number of beam rows in the allotted acquisition period based on a condition that a total time to search the number of beam rows is less than the maximum allowable search time. 13. The system of claim 10, further comprising a radar mode unit that is electrically coupled to the radar beam control, wherein the radar mode unit sends instructions to the radar beam control to operate in a different mode based on the condition that the number of beam rows in the allotted acquisition period is expanded to at least one outer row. 14. The system of claim 13, wherein the radar beam control estimates the maximum extent that is searchable by the number of beam rows in the allotted acquisition period based on the instructions received from the radar mode unit. 15. The system of claim 14, wherein the radar beam control adds an elevation pad to an extent sent.
