The government will provide In-Phase Quadrature (I/Q) data collection files that represent radar and ECM responses for RFCM test scenarios to be analyzed. Data will be provided via classified media. Every test scenario will either include (a) description/model of the expected ECM or (b) trusted collection that contains an ECM response that will be used to generate limits. These limits will then be used to compare test results for other data collections for this test scenario. The prime objective is for the contractor to highlight all of the areas where the ECM response went outside of the expected tolerances in order for the government to do further investigation or document problems with the SUT. Below is a list of tasks required:

The contractor shall import I/Q formatted binary files that contain radar and Electronic counter measures baseband I/Q sample data.

2.1.2. The contractor shall provide advanced electronic countermeasure (ECM) analysis for multiple false target (MFT) techniques.

2.1.3. The contractor shall separate and analyze false targets independently.

2.1.4. The contractor shall analyze up to 20 false targets in parallel.

2.1.5. The contractor shall perform required advanced analysis of each false target includes range, velocity, amplitude, amplitude modulation (modulation rate and duty cycle), pulse width, blanking, and percent jamming characteristics. The contractor shall ensure all frequency analyses have frequency accuracy better than 150 Hz.

The contractor shall analyze all pulses with PWS of 100 ns or more.

2.1.7. The contractor shall perform analysis on pulsed and CW signals.

2.1.8. The contractor shall model expected ECM results for each false target. Government will provide expected ECM characteristics and allowable tolerances for each false target.

2.1.9. The contractor shall generate interactive graphs that plot actual results (range, velocity, etc.) versus allowable limits. Interactive graphs must have zoom and pan capabilities.

2.1.10. The contractor shall display data and limits for each false target on separate graph layers so that false targets can be turned off and on.

2.1.11. The contactor shall evaluate results versus limits and display all failing data points in red.

2.1.12. The contractor must be able to process I/Q data representing an instantaneous bandwidth (IBW) up to 125 MHz with collection times up to 30 seconds.

The contractor will provide a final engineering report containing all ECM analysis, models, results, graphs and data produced by the tasks above. Additionally the contractor will provide all digital analysis products, models, and software developed under this contract in a Software Test Report
