Appl. No.:

16/202737

Inventors:

- Bethesda MD, US
Nicholas J. Romano - Collingswood NJ, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

Abstract:

Radar signals are generated to have signal characteristics that define multiple sub-pulses in each of a plurality of pulse repetition intervals (PRIs) of a single radar dwell. Electromagnetic radiation is emitted according to the radar signals and the emitted electromagnetic radiation is sensed as radar return signals over a receive interval in each PRI. Coherent integration is performed on a set of the radar return signals and non-coherent integration is performed on another set of the radar return signals.

Abstract:

A system for measuring structural integrity includes a self-contained rapid modal testing trailer that delivers an impact load to a structure being tested and records data resulting from the impact load, and a data processing software that extracts modal parameters of the structure, such as frequencies and mode shapes. The parameters are used to determine anomalous behavior as well as provide experimental data for finite element model calibration.
