Statement of Work RF Control Hardware 02/23/2017
1.0 Scope/Background
In order to meet current and future requirements of Naval Air Warfare Center Weapons Division, China Lake (NAWCWD), the RF Systems and Development branch (Code 472200D) is upgrading the Ka-Band Instrumentation Radar (KBIR). The Government intends to procure two (2) waveform generators. The components shall be used for signature collection or radar cross section of UAVs and are necessary to support the waveform that will be used in the upgraded KBIR.
2.0 Applicable Documents
None
3.0 Requirements/Specifications
The following describes the specifications for the two (2) waveform generators to be procured, which will consist of two (2) Arbitrary Waveform Generators. Each device shall be capable of meeting the requirements of upgrading an existing Ka-Band instrumentation radar. All specifications are the minimum requirements unless otherwise stated.
