3). A circulator is usually employed to direct the transmitter signal to the array element and the received signal from the array element to the LNA. Additional devices may be used to provide further receiver protection. 5 degrees, for a typical 4-bit phase shifter. This is accomplished by switching delay-line segments with incremental lengths into and out of the signal path using diode switches. The signal attenuator is often also a binary device that switches the various increments of attenuation into and out of the signal path.

These can include losses from the atmosphere (Sec. 1), rain (Sec. 2), and the ionosphere (Sec. 6). • Two-way off-broadside scan loss for phased array antennas (Sec. 1). • Signal-processing losses, including departure from an ideal matched filter, quantization error, integration loss, straddling range or Doppler bins, signal distortion, and CFAR setting loss. 2 Signal-to-Noise Ratio 39 Transmit and receive antenna loses, including ohmic loss and aperture efficiency loss, are normally included in the corresponding gain and effective aperture area parameters.

The antenna rotates continuously in azimuth, usually at a constant rate, providing 360-degree search coverage with a rotation period typically 10 to 20 seconds. The elevation-angle coverage is tailored to match the targets of interest. Maximum gain is usually provided at low elevation angles. The gain is often reduced at higher elevation angles to provide coverage only to maximum aircraft altitudes, typically 10 to 15 km.
