Active antenna array concepts for precision approach radar

Triple-Radiation Pattern Monopulse Horn Feed With Compact Single-Layer Comparator Network

“…S INCE it was initially conceived [1], radar technology has experienced an enormous development and nowadays it constitutes the keystone of a wide range of different applications. These are found not only in the military area [2], [3], but also in other civil scenarios like air traffic control [4], [5], remote sensing [6], [7], the automotive sector [8], [9], meteorology [10], [11] or space debris detection among others [12], [13]. In Ka-band, as the design in this paper, different radar applications are found, like airport surveillance or traffic enforcement cameras activated by radar [14]- [16].…”

System for Automatic Detection and Analysis of Targets in FMICW Radar Signal

“…The spectrum is calculated according to (2). YuleWalker equations can be used for the calculation as described in [8].…”

“…The second part is the receiver, which is composed of the PIN diode, mixer and analog to digital converter (ADC). For the signal transmission and receiving one antenna setting described in [1], or antenna array described in [2] can be used. Universal scheme is in Fig.…”
