The direct path distance from the transmitter to the receiver can vary from a few kilometers to 100 km.

Digital TV signals are also commonly used in areas where they are available.įigure 2 illustrates the elements of a PCL radar, where R t is the transmitter-to-target distance and R r is the target-to-receiver distance. They are available worldwide, and the signal bandwidth (50–100 kHz) and power (typically, 100–250 kW) are adequate. The most common transmitters used in existing PCL systems are FM radio stations. Signals of opportunity can be radio or TV broadcasts, including both analog and digital TV, mobile telephone networks, local area networks, and even satellite transmissions. The unique feature of PCL radars is their use of signals of opportunity. This is in contrast to the more common monostatic radars having a transmitter that is colocated with or near the receiver. PCL radars are a variation of bistatic radars, which are radars in which the transmitter and receiver are not colocated. Adding a PCL radar to the T 2OURNAMINT test environment will enable the development of countermeasures to this unique, emerging PCL radar threat. A key element of this test environment is the Testing Theater Operations Using Real-time Networks Achieving Multiple Interconnected Nodal Tactics (T 2OURNAMINT) system, which serves as the hub of a digital electronic warfare (EW) environment. Naval Air Warfare Center Weapons Division (NAWCWD) provides a simulation of contested environments enabling the testing of new and emerging systems against realistic threats and threat scenarios.
