Planar arrays provide directional beams, symmetrical patterns with low side lobes, much higher directivity (narrow main beam) than that of their individual element. In principle, they can point the main beam toward any direction. Applications – tracking …

Planar Array. These phased array antennas consist completely of single elements with a phase shifter per element. The elements are arranged like a matrix, the flat arrangement of all elements forms the entire antenna. Advantage: beam deflection possible in two planes; Disadvantage: a large number of phase shifters

an introduction to the specific features of radar phased array antennas and the associated signal processing following the description of [1]. First the radar principle and the terminology is explained.

Planar Array Radars: The planar array, radar uses a high-gain planar array antenna. A fixed delay is established between horizontal arrays in the elevation plane.

Compared with conventional two-dimension spacetime adaptive processing (2D-STAP) methods, elevation-azimuth- Doppler three-dimension STAP (3D-STAP) method has the advantage of suppressing...

Planar Array — This example is a rectangular 4 × 16 element lattice with l/2 spacing, N x = 16, N y = 4, d x = d y = l/2. This array also uses a Dolph-Chebyshev taper for 40 dB sidelobe ratio in the x direction. The layout of the elements and results of the simulation are illustrated in Fig. 5, showing a HPBW of 12.1º.

The frequency diverse array (FDA) radar has been extensively studied due to its unique range-angle dependent beampattern. Time-invariant spatial patterns have been reported for FDAs proposed so...

Calculate the normalized array factor for an array of 3 isotropic radiating elements. They are located along the x-axis (center one at the origin) and spaced λ / 2 apart. Relevant information is 2 and 3 viewgraphs back.

Directive antenna array with reduced side lobe level can be obtained using thinned array. This paper describes the design of planar thinned array using Hadamard matrix-like arrangement.
