The radar "looks" with the looking angle θ (or so called off-nadir angle). The angle α between x-axis and the line of sight (LOS) is called cone angle, the angle φ between the x-axis and the projection of the line of sight to the (x; y)-plane is called azimuth angle. Cone- and azimuth angle are related by cosα = cosφ ∙ cosε.
The AN/APG-66 radar is an X-band [1] solid state medium range (up to 80 nautical miles (150 km; 92 mi)) pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation (now Northrop Grumman) for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83.
A pencil-beam radar A moving or sweeping pencil-beam radar. In optics, a pencil or pencil of rays, also known as a pencil beam or narrow beam, is a geometric construct (pencil of half-lines) used to describe a beam or portion of a beam of electromagnetic radiation or charged particles, typically in the form of a cone or cylinder.
The AN/APG-68 radar is a long range (maximum detection range 80 kilometres [50 mi]) [2] Pulse-Doppler radar designed by Westinghouse (now Northrop Grumman) to replace AN/APG-66 radar in the General Dynamics F-16 Fighting Falcon. The AN/APG-68 radar is now currently being replaced on US Air Force F-16C/D Block 40/42 and 50/52 by the AN/APG-83 ...
The AN/APY-10 is an American multifunction radar developed for the U.S. Navy's Boeing P-8 Poseidon maritime patrol and surveillance aircraft. [1] AN/APY-10 is the latest descendant of a radar family originally developed by Texas Instruments, and now Raytheon after it acquired the radar business of TI, for Lockheed P-3 Orion, the predecessor of P-8.
The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
The radar is designed with high resistance to electronic countermeasures (ECM) and anti-radiation missiles (ARM). [ 1 ] The system automatically acquires, tracks, classifies , identifies and reports high- and low-altitude targets, including cruise missiles , unmanned aerial vehicles , and both rotary- and fixed-wing aircraft .
A new methodology was developed in May 1942, combining an S-band airport surveillance radar (ASR) that brought the aircraft into the general area of the airport, and a second X-band radar, the precision approach radar (PAR), with separate antennas for vertical and horizontal guidance that were moved in such a way to avoid seeing the ground.
