  2. Continuous-wave radar - Wikipedia

    en.wikipedia.org/wiki/Continuous-wave_radar

    Continuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. [1] Individual objects can be detected using the Doppler effect , which causes the received signal to have a different frequency from the transmitted signal ...

    The diagram on the left shows the effect on the spectrum if a trapezoid pulse profile is adopted. It can be seen that the energy in the sidebands is significantly reduced compared to the main lobe and the amplitude of the main lobe is increased. Radar transmission frequency spectrum of a cosine pulse profile

  4. Phased array - Wikipedia

    en.wikipedia.org/wiki/Phased_array

    Fixed phased arrays incorporate fixed phase shifters. For example, most commercial FM Radio and TV antenna towers use a collinear antenna array, which is a fixed phased array of dipole elements. In radar applications, this kind of phased array is physically moved during the track and scan process. There are two configurations.

  5. Radar engineering - Wikipedia

    en.wikipedia.org/wiki/Radar_engineering

    Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.

  6. AN/AWG-9 - Wikipedia

    en.wikipedia.org/wiki/AN/AWG-9

    The AN/AWG-9 offers multiple air-to-air modes: long-range continuous-wave radar velocity search, range-while-search at shorter ranges, and an airborne track-while-scan mode with the ability to track up to 24 airborne targets, display 18 of them on the cockpit displays, and launch against 6 of them at the same time. This function was originally ...

    en.wikipedia.org/wiki/Radio_receiver_design

    Here we show block diagrams for typical superheterodyne receivers for AM and FM broadcast respectively. This particular FM design uses a modern phase locked loop detector, unlike the frequency discriminator or ratio detector used in earlier FM receivers. A schematic of a simple superhet broadcast FM receiver.

  8. Bistatic radar - Wikipedia

    en.wikipedia.org/wiki/Bistatic_radar

    Bistatic radar block diagram Bistatic Radar Passive Receiver System from NCSIST of Taiwan. Bistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a ...

    en.wikipedia.org/wiki/AN/SPG-62

    The AN/SPG-62 is a continuous wave fire-control radar developed by the United States, and it is currently deployed on warships equipped with the Aegis Combat System. [1] It provides terminal target illumination for the semi-active SM-2MR/ER and ESSM Block 1 surface-to-air missiles.
