But three potential LPI receiver architectures -- channelized, superhet
and acousticoptic with narrow RF and video bandwidths -- show the potential to provide the sensitivity and capability required in an environment where both conventional and LPI signals are present.
The STAR product line includes channelized receivers, high-resolution cued superhet
receivers and state-of-the-art parameter encoding preprocessing.
These include improvements to the ALQ-149's superhet
receivers, which will upgrade the equipment's technology and reliability/ maintainability.
The compact subsystem uses a high-gain rotating antenna together with a wideband, coherent superhet
The equipment comprises a programmable superhet
receiver, a digital pulse analyzer and a high-gain wide-band dish antenna.
