The Prowl Surveillance Kit is a low-power, battery-operated, portable radar that detects targets within foliage. It also detects human and vehicle targets. The radar will operate in the radiolocation service. The Air Force intends to use this system for Stage 4 operations at Fort Huachuca, AZ. The Air Force plans to procure 100 radios. The estimated initial cost of this system is $35,000. Table 1 below summarizes this system's spectrum requirements. Table 1: Prowl Surveillance Kit's Spectrum Requirements Requested Bands Requested Emission Peak Power Stage 4 (MHz) Designator (W) Station Class Symbol 5764 320MPON 2.13 MR Spectrum support issues/certification are discussed hereinafter. References to the NTIA Manual are for September 2015 Revision of the May 2013 Edition.

Table 2: Preliminary Assessment Findings ISSUES FINDINGS REMARKS Data y N Adequacy lz;J D Adequate per Chapter 10 of the NTIA Manual: Submitted to SPS for review in August 2016. Allocation Compliance: The frequency range 5604-5924 MHz (center Federal Allocations frequency 5764 MHz) falls within two federal allocation bands 5600-5650 MHz and 5650-5925 MHz that are allocated on a primary basis to the federal radiolocation service. Pertinent Footnotes: G2: In the band 5650-5925 MHz, use of the Allocations Operations in the Radiolocation Service in the Frequency Range Federal radiolocation service is restricted to the Conformance 5604-5924 MHz (Center Frequency 5764 MHz): military services. G56: Federal radiolocation in the band 5350-5650 5600-5650 MHz MHz is primarily for the military services 5650-5925 MHz y N G131: Federal stations in the radiolocation service iz;J D operating in the band 5470-5650 MHz shall not cause harmful interference to, nor claim protection from, Federal stations in the maritime radionavigation service. 5.150: The band 5725-5875 MHz (center frequency 5800 MHz) is designated for industrial, scientific and medical (ISM) applications. Radiocommunication services operating within this band must accept harmful interference which may be caused by these applications. ISM equipment operating in these bands is subject to the provisions of No. 15.13.

Snecified (Radar Receiver Selectivitv): The Air Force indicated that this system uses a hormodyne receiver so an IF signal is not generated. The Air Force also indicated that the eceived signal is directly converted to a baseband signal. NTIA Reauirement: Section 5.5.7.1 states "The overall eceiver selectivity characteristics are commensurate with the transmitter bandwidth."
