Conventional array radars typically employ either mechanically scanned or electrically scanned, i.e., phased array radars. The mechanical scanning radar realizes beam scanning by rotating a radar antenna, and is influenced by mechanical rotation, so that the mechanical scanning radar is slow in response speed, low in target updating rate, poor in resolution, weak in multifunctionality, poor in electronic countermeasure capacity, large in size, high in power consumption and high in price. Although the electric scanning type radar, namely the phased array radar, flexibly controls the beam direction by controlling the feeding method of the antenna array element, the beam direction is flexible, inertia-free rapid scanning can be realized, the data rate is high, and the resolution, the versatility and the electronic countermeasure capability are strong, however, the traditional phased array radar is expensive, large in power consumption, large in volume and large in cooling requirement. This is because each antenna element in the phased array radar includes necessary devices such as a phase shifter in addition to the antenna element. Different elements can be fed with currents of different phases through phase shifters, thereby radiating beams of different directivities in space. The basis of the operation of such a radar is a phased array antenna. The mechanical scanning and the electric scanning are completed by controlling all directions of the antenna unit.
The working basis of the electric scanning type radar antenna is an array antenna with controllable phases, each antenna unit is provided with necessary devices such as a phase shifter and the like besides an antenna oscillator, and different oscillators can be fed with currents with different phases through the phase shifter, so that beams with different directivities are radiated in space; the traditional array radar usually adopts a mechanical scanning type or an electrical scanning type, namely, a phased array radar, the mechanical scanning type radar realizes beam scanning by rotating a radar antenna, and because the mechanical scanning type radar is influenced by mechanical rotation, the response speed is slow, the target updating rate is low, the resolution ratio is poor, the versatility is weak, the electronic countermeasure capability is poor, the size is large, the power consumption is high, and the price is high.
