Radiolocator Design: High-Frequency Front End

Chapter

Abstract

We have seen in Chaps. 2 and 3 that the direction of an incoming wave can be reconstructed from the interaction of that wave with an assembly of directional antennas of known characteristics. In this chapter, we begin to look at the engineering aspects of collecting data from the antennas, and, in the spirit of good design practice, we will outline the system requirements and consider some plausible architectures.

The overarching requirement in our entire radiolocation work is that the direction of the incoming wave be obtained for every wireless packet, and that the direction be assigned to that packet before the next one arrives, i.e., at the rate of wireless traffic. Two requirements follow:

(1) Signal strengths on all antennas must be captured during the passage of the packet. Antenna signals must be captured consistently, that is, they must all be measured at the same (average) carrier amplitude.

(2) Logical content of the packet must be decoded as usual, i.e., networking communication must not be impeded by radiolocation.
