Abstract:

A system, method, and computer program product are provided for invoking an operation to change a current data row of a table in a local database. As a result, a pending change data row is inserted in the table, distinguished by a primary key comprising a common key value and a pending change indicator. The pending change is then submitted for synchronization.

Abstract:

A method for mitigating low duty factor electronic attack (EA) includes taking M samples of each of N pulses of radar return energy. The method includes forming an M×N pulse sample data matrix (PSDM) using the M samples and N pulses of the radar return energy including in-phase and quadrature phase components of the radar return energy and jamming data from the low duty factor EA. The method includes defining a 2N×1 vector for each row of the PSDM. The method includes computing a 4N×1 vector separating the in-phase and quadrature phase measurements of the jamming data from the low duty factor EA into a respective half of the 4N×1 vector using the 2N×1 vector and a measurement matrix dictionary. The method includes extracting the jamming data from the 4N×1 vector and forming a clean M×N PSDM that is free of the jamming data using the 4N×1 vector.
