Abstract: Low-frequency radars operating in the VHF and UHF bands, like the AN/APY-9 on-board the E-2D Hawkeye can detect and even track low-observable aircraft. But historically, UHF radars had resolution and detection issues that have made them ineffective for accurate targeting and fire control. Higher frequency radars provide the benefit of higher angular resolution. Migrating to higher frequencies (S-band) can enable weapons quality, high-resolution target tracks from the radar, thus guiding missiles accurately to the target. Higher frequencies also result in higher peak transmit power for radar systems to meet the link budget. Hence the Transmit-Receiver (T/R) modules that support these frequencies to build a complete phased-array radar system need to be designed with high power-density to obtain desired Equivalent Isotropically Radiated Power (EIRP). IAI proposes a modular, low-profile MSPAR design to address this problem, and will meet the functional and operation requirements for Nay airborne radars.
Benefits: Commercial applications of MSPAR include: ? Enabler for AAS in 5G and newer mobile networks. ? Multi-Protocol, Heterodyne, Direct-digital Communications Receivers (GPS/GNSS, Cell-phone) ? Synchronized multi-channel receivers for cell-phone or asset tracking
