This standard is approved for use by the Department of the Navy and is available for use by all Departments and Agencies of the Department of Defense. 2. The increased use of electrical and electronic equip
3、ments and sensors aboard Naval ships introduces risk of Electromagnetic Interference (EMI) that can impact compliance with the ships Electromagnetic Environmental Effects (E3) performance requirements specified in MIL-STD-464. 3. This revision of MIL-STD-1605 has been expanded to provide the procedu
4、res and techniques for assessing compliance with the intra and inter-system Electromagnetic Compatibility (EMC) and Intermodulation Interference (IMI) requirements of MIL-STD-464 for naval surface ships. However, adherence to the procedures contained herein does not relieve the contractor from meeti

31、 An area on ships which is surrounded or partially surrounded by a metallic structure, or an area which provides adequate attenuation to electromagnetic (EM) radiation, such as the metal hull or superstructure of a surface ship, and the screened rooms in non-metallic ships. 3.3 Broadband antenna. An
32、 antenna that has a relatively constant gain, and that functions satisfactorily, over a wide range of frequencies (2:1 or greater bandwidth range), such as a log periodic or horn antenna. 3.4 Electromagnetic compatibility. The ability of electrical and electronic systems, equipment, and devices to o
33、perate in their intended operational environments without suffering unacceptable degradation or causing unintentional degradation because of electromagnetic radiation or response. It involves the application of sound electromagnetic spectrum management; system, equipment, and device design configura
34、tion that ensures interference-free operation; and clear concepts and doctrines that maximize operational effectiveness. 3.5 Electromagnetic interference. Any electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical e
35、quipment. EMI can be induced intentionally, as in some forms of electronic warfare, or unintentionally, as a result of spurious emissions and responses, intermodulation products, and the like. 3.6 Equipment, electrical. Equipment, other than electronic equipment, designed to generate, convert, distr
36、ibute, control, or utilize electrical energy. Examples are generators, power switchboards, motor controls, motors, lighting fixtures, and electrical appliances. 3.7 Equipment, electronic. Equipment designed to generate, transmit, convey, receive, store, process, or otherwise use electronic/digital s
37、ignals. Examples are oscillator equipments, transmitters (sonar, communication transmitters, and radar), amplifiers, sensing devices, receivers, digital equipment, underwater detection equipment, fire control equipment, drone control equipment, and associated test equipment. 3.8 Intermodulation. The
38、 production in a nonlinear element of frequencies equal to the sums and differences of integral multiples of two or more frequency sources. 3.9 Phase I tests. That part of the EMI survey, specified herein, that is conducted dockside for the purpose of keeping the Phase II (underway) test time to a m
39、inimum. Phase I tests measure the impact from unintentional electromagnetic emissions of installed electrical/electronic equipment on wireless radio frequency (RF) sensor type electrical/electronic equipment. This requires the measurement of the emissions received by RF sensors to determine whether
40、these unintentional electromagnetic emissions are a potential source of interference. In addition, Phase I tests determine the susceptibility of equipment/systems to ships portable communication transmitters by keying the portable units within 18-inches of equipment/systems. 3.10 Phase II tests. Tha
41、t part of the EMI survey, specified herein, that determines the EMC of the ships electrical/electronic systems. Phase II tests are conducted while the ship is underway and in a typical operating configuration with all below deck and topside emitters on and operational. Emission and susceptibility te
42、sts not able to be performed during Phase I should be completed at the beginning of Phase II. 3.11 Susceptibility. The inability of an item to perform its function without degradation while in the presence of an EM disturbance. EM disturbances can be in the form of either radiated or conducted emiss
43、ions. 3.12 Topside areas. An area on ships, which is directly exposed to the external electromagnetic environment, and is not considered to be below deck as defined herein. 3.13 Unintentional emissions. An emission from a device that generates RF energy for use within the device, and sends RF signal
44、s by radiation to other devices nearby or by conduction to associated equipment via connected wiring, despite the fact that it is not intended to emit RF energy by radiation or conduction. 4. GENERAL REQUIREMENTS 4.1 General. MIL-STD-464 requires that a ship shall be self compatible. This standard r
45、equires that a ship meets its operational performance requirements when all of the ships equipment/systems are operating together at their designed level of efficiency or their designed capability. All tests specified in this standard are to demonstrate EMC between shipboard systems/equipment/sensor
46、s. 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-1605A(SH) 4.1.1 System/sensors/receivers. System/sensors being measured shall not be adversely affected by unintentional emissions. Topside Medium Frequency (MF), High Frequency (HF), Very
47、High Frequency (VHF) and Ultra High Frequency (UHF) receive systems shall not be degraded by ownship unintentional emissions. Electrical/electronic equipment/sensors shall not be susceptible to own ship portable or fixed intentional radiating equipment/systems, or unintentional emitters (equipment/s
48、ystems). 4.1.2 Hull generated IMI. MIL-STD-464 specifies the applicable requirements for hull-generated IMI. IMI tests shall be conducted on ships that contain HF broadband antennas, and/or ships that contain two or more HF narrow band transmit antennas. When HF narrow band antennas are tested for I
49、MI all possible antenna combinations shall be tested. IMI products above the 19thorder shall be located and mitigated. 4.1.3 All up system to system test. To assess compliance with MIL-STD-464, “All Up Systems to Systems Test” shall be conducted by evaluating systems interaction and/or compatibility with other ship systems, and identifying EMI victim systems when all ship systems are fu
