Woodward constant with space-distance resolution in radar scanning system

Cylindrical array as a means of the clutter suppression via scanning acceleration and space-time signal processing

“…Only AP in the scanning plane (in the azimuth plane) has the substantial consequence for the space clutter suppression with accelerated scanning [1][2][3][4][5][6][7][8]. For a rectangular plane array, such AP (see above) is determined by horizontal linear array characteristics (i.e., subarray of plane array), and for a cylindrical array, it is determined by ring subarray characteristics.…”

“…Analysis and optimization of the signal processing for the scanning radar system with quasi-continuous radiation are made in our works [1][2][3][4][5][6][7][8]. The use of quasi-continuous radar radiation is an effective way to improve moving target extraction from clutter [9], i.e., time (Doppler) signal processing.…”

“…In these both cases, intense clutter at short and medium ranges acts simultaneously with the weak useful signals from the farthest targets. For such conditions, it is expedient [1][2][3][4][5][6][7] to suppress the clutter by space signal processing at high scanning rate in the azimuth plane (i.e., scanning acceleration compared to the traditional rate values) when the scanning antenna pattern (AP) rotates through an angle of the AP width order per time s t .…”
