EXHIBIT 3 COORDINATION WITH FEDERAL AVIATION ADMINISTRATION (FAA) CHEMRING SENSORS AND ELECTRONIC SYSTEMS, INC. APPLICATION FOR MODIFICATION OF EXPERIMENTAL LICENSE CALL SIGN WG2XMT FILE NO. 0231-EX-CM-2017 Chemring Sensors and Electronic Systems (“Chemring” or “CSES”) seeks a modification to its existing experimental license (Call Sign WG2XMT, File No. 0327-EX-PL-2013, granted Nov. 26, 2013) to change its testing locations. In particular, Chemring seeks to remove the two testing locations in Charlottesville, Virginia, and replace them with one testing location in Charlotte, North Carolina. (The other testing location in Dulles, Virginia, remains the same.) Chemring previously filed an application for modification that was dismissed without prejudice due to Federal Aviation Administration (“FAA”) concerns regarding potential interference (Call Sign WG2XMT, File No. 0034-EX-CM-2017, dismissed without prejudice July 24, 2017). Chemring has coordinated with the FAA regarding its concerns and the FAA has conditionally concurred with Chemring’s application via correspondence dated Sept. 7, 2017. Please see the attached. In addition, please note that the statement requested by Mr. Murphy (“Due to emission levels exceeding the required limits per FCC Part 15 and NTIA Annex K in the 960-2210 MHz range, the proponent will operate with lower power and/or shielding to reduce risk to nearby FAA operations.”) has been added to Exhibit 1, Testing Location Descriptions, and Exhibit 2, Government Project Description and Public Interest Statement.

Please add the following statement: Due to emission levels exceeding the required limits per FCC Part 15 and NTIA Annex K in the 960‐2210 MHz range, the proponent will operate with lower power and/or shielding to reduce risk to nearby FAA operations. This is especially important for Dulles since the location is within the required distance separation.

From: rodney.murphy@faa.gov [mailto:rodney.murphy@faa.gov] Sent: Friday, August 11, 2017 2:44 PM To: Browne, Maria Subject: RE: OET Experimental License Dismissal Notification, Call Sign: WG2XMT File Number: 0034-EX-CM-2017 Since 2012, the FAA has consistently provided objections to Husky GPR operations at both Dulles, VA, Charlottesville, VA and Charlotte, NC. This was done under NIITEK ownership. Various comments were given, such ensuring that the emissions will be under FCC Part 15 rules for UWB, to notching out critical FAA aviation bands (108‐137 MHz, 328.6‐ 335.5 MHz, etc). Can the proponent provide information about the emissions masking and any possible shielding to ensure that the power levels are not excess and harmful? In other words, how much power will actually be emitted, and can previous conditions (such as frequency notching) be utilized as necessary?

EXHIBIT 3 August 22, 2017 Rodney Murphy Federal Aviation Administration Spectrum Engineering and Policy Fixed/Land Mobile, UAS, Satellite, Experimentals FAA FAS Representative Re: CSES Time Domain Impulse Radar Mr. Murphy: Pursuant to your request, attached please find information provided by Chemring Sensors responding to your questions concerning the CSES (formerly NIITEK) Time Domain Impulse Radar (“GPR”). Specifically, the attached includes an explanation of the technology employed by the GPR, as well as a description of the GPR’s emissions and power levels, the methods employed by Chemring to minimize the GPR’s interference potential, the extensive testing conducted by Chemring in conjunction with its military partners, and its numerous years of experience operating the GPR without any instances of interference, including operation in close proximity to airports. Please let know if we can provide any additional information to assist in your analysis of the GPR. Sincerely, Maria Browne
