AN/SPS-8 is a two-dimensional radar manufactured by General Electric . It was used by the US Navy as a height finding radar after World War II , and was equipped aboard naval ships during the Cold War . Variants include AN/SPS-8A , AN-SPS/8B , AN/SPS-8C and AN/SPS-8D After modernization, it was redesignated as AN/SPS-30 .
7-461: It worked in two modes in terms of range - with a pulse frequency of 1000 Hz (pulse duration 1 μs, range 154 km) and 500 Hz (2 μs, 308 km). In a real situation, the F2H aircraft was detected at a distance of 111 km (SPS-8A / B modifications - 133 km). The target elevation angle was determined by scanning the beam in the vertical plane with a frequency of 5, 10 or 20 Hz (in
14-637: A narrow beam through a scan pattern to build a 3-D picture. Examples include NEXRAD Doppler weather radar (which uses a parabolic dish) and the AN/SPY-1 passive electronically scanned array radar employed by the Ticonderoga class of guided missile cruisers and other ships so equipped with the Aegis Combat System . Stacked beam radars emit and/or receive multiple beams of radio waves at two or more elevation angles. By comparing
21-585: The SPS-8 was the CXRX radar, 3D radar 3D radar provides for radar ranging and direction in three dimensions. In addition to range, the more common two-dimensional radar provides only azimuth for direction, whereas the 3D radar also provides elevation. Applications include weather monitoring , air defense , and surveillance. The information provided by 3D radar has long been required, particularly for air defence and interception . Interceptors must be told
28-597: The SPS-8B modification -6, 12 and 16.5 Hz). The accuracy of determining the height was 150 m. The deflection of the beam in elevation was carried out by a Robinson Scanner feed in modifications SPS-8 and SPS-8A and an organ-type feed in modification SPS-8B In the SPS-8A modification, the capacity was increased from 650 kW to 1 MW with a design capacity of 2 MW. In the 2-μs pulse mode, pulse repetition rates of 450 and 750 Hz were provided. The SPS-8 and SPS-8A used
35-509: The SPS-8B, the best American sweeping beam radar, the SPS-30, was created, which used a high gain antenna and a 2.5 MW klystron. Work on its creation began in 1956. It is a three-dimensional radar . It was planned to upgrade the SPS-8 and SPS-8A to SPS-8C / D with the installation of the same antennas and klystrons as on the SPS-30, but these plans were not implemented, although at the end of 1957, 30 new antennas were produced. A modification of
42-405: The altitude to climb to before making an intercept. Before the advent of single unit 3D radars, this was achieved with separate search radars (giving range and azimuth) and separate height finding radars that could examine a target to determine altitude. These had little search capability, so were directed to a particular azimuth first found by the primary search radar. Steered beam radars steer
49-615: The same mesh antennas. SPS-8B, first tested in January–June 1956 and put into service in 1959, had a high gain antenna (41 instead of 37.4 dB), a narrower beam (1.2 ° × 1.5 °) wider scanning sector in elevation (12 °) at a vertical scanning frequency of 6, 12 and 16.5 Hz. The information was displayed on the VK circular view indicator (Model VK Plan Position Indicator) and the VL range-height indicator (Model VL Range-Height Indicator). Based on
