Radar receivers have to be tuned to the precise frequency of the transmitter, in order to get the best detection and thus the best picture. The transmitter generates microwaves from a device called a magnetron. The exact frequency can vary with age and temperature. To pick up the echo generated from the pulsed microwave, the receiver is able to be tuned, to allow for differences in transmitter frequency. The control on the radar receiver display, called 'tuning', actually alters the receiver frequency, not the transmitter frequency.
A radar engineer works with radar. They have design, develop, install, and test a radar.
Radar range is the distance of the object from the radar. Radar bearing is the direction of the object in relation to the radar. As radar is primarily used for ranging, the range information may be more important than the bearing.
An FMCW radar may make use of Doppler, but it doesn't necessarily.
Microwave IS used in RADAR.

The company Sonicview manufactures products for television viewing such as satellite receivers, wireless receivers, cable receivers, and Dolby digital receivers.

Basically there are no physical limitations of wavelength where a RADAR unit may operate, thereby it can operate practically on any wavelength from ELF (extremely low frequency) where wavelength can be as high as several hundreds kilometers or in Optical band like Laser RADAR (LADAR) who have wavelength of some microns . The limitations of RADAR operating wavelength is in their geometrical size of devices (transmitters, antennas and Receivers) required to produce such wavelength and their utilization . The following list is typical wavelength used by RADAR applications Search and Early Warning RADAR : >1- 10cm wavelength (HF- C band) Target Tracking RADAR : <10 cm Wavelength (C-band till milimmetric waveband) hope this helps
Free sat receivers are sold in the United Kingdom. I did not find any receivers for sale in Virginia.

Some common reception problems with satellite tv could be- bad weather, tree blockage, objects sticking to your Dish, radar interference, dysfunctional distribution amplifier and locked up receivers.
