With constant impedance, the current is proportional to the voltage so that power is proportional to the voltage multiplied by its complex conjugate. The peak of the autocorrelation function is always real. For nonperiodic waveforms, the envelope tends to a steady line. The energy per second gives the power. 5 x Cross-correlation function (as a function of displacement x) . 11 Polyphase power representation. In order to remove the carrier and preserve all the amplitude and phase information, the real and imaginary components of the modulation must be determined.
Mapping over a number of scans is also described. 11 Threshold The bases for decisions whether the radar detects an object are described in Chapter 12. They are described in terms of a steady scatterer (Marcum model) and the four Swerling model scatterers. 12 Determination of position Once the decision is made as to whether something is there, the best estimation must be made for its location. Methods and the accuracy obtained are described in Chapter 13. 13 Common components and timing The components in a radar must operate together and in proper time, so every radar needs a number of control pulses or triggers.
So far, the integrated circuit components used for signal processing are made for Cartesian components, so polar detectors are a curiosity. 13 is a block diagram of such a detector. 13 Block diagram of a polar detector. The term “second detector” comes from superheterodyne radio receivers and this is the stage where the modulation is recovered (see Chapter 9, Detectors). 5 SYMMETRICAL COMPONENTS IN POLYPHASE CIRCUITS Other than synchros, motors that drive fans, and power transformers, there are physically no polyphase components used in radar.
