Two-dimensional pulse integration method

A two-dimensional pulse integration method comprising:

• a reference data extraction step of extracting m×N pieces of reference data for each azimuth of m consecutive range bins, including the pth range bin for the pth pulse integral of the received radar signal;
• a data sorting step of sorting the extracted m×N reference data in ascending order of size;
• an erasing step of erasing the first N1 reference data and the last N2 reference data among the sorted reference data;
• and
• an integration step of summing all the remained reference data values after erasing are performed according to [Equation 4] and [Equation 5].

A two-dimensional pulse integration method comprising:

• a first reference data extraction step of extracting m1×N reference data for each azimuth of m1 consecutive range bins that include the pth range bin and are continuous up to the pth range bin for the pth pulse integral of the received radar signal;
• a first data sorting step of sorting the extracted m1×N first reference data in ascending order of size;
• a first replacement step in which all reference data after the k1th reference data among the sorted reference data are replaced with the k1th reference data value;
• a first integration step of summing all the reference data values after replacement;
• a second reference data extraction step of extracting m2×N reference data for each azimuth of m2 consecutive range bins that include the pth range bin and continuous from the pth range bin;
• a second data sorting step of sorting the extracted m2×N second reference data in ascending order of size;
• a second replacement step in which all reference data after the k2th reference data among the sorted reference data are replaced with the k2th reference data value;
• a second integration step of summing all the reference data values after replacement, and
• a minimum value selection step that adopts the smaller value between the results of the first integration step and the second integration step.
