Radars are conventionally operated as a monostatic radar with the transmitter and the receiver at the same location. In the case of a bistatic radar the transmitter. Unless the separation between transmitter and receiver is small compared with ranges of interest, bistatic radars have a number of properties which differ. Among the topics discussed are the type of information available from the received signal, methods for extracting information from the bistatic radar signal.

By receiving the side lobes of the transmitting radars direct beam, the receiving sites radar can be synchronized.

If the main lobe is detected, an azimuth information can be calculated also. A bistatic radar of specialized bistatic systems are in use, for example, where multiple receiving sites are used to correlate target position.

Remember that the helicopters rotor has a speed limit a little bit less than sonar speed at the rotor endsa special spectrum of Doppler frequencies gives information about the actual flight phase and the course of the helicopter. Bistatic radar radar Bistatic radar bistatic or multistatic radar that exploits non-radar transmitters of opportunity is termed a passive coherent location system or passive covert radar.

Any radar which does not send bistatic radar electronic magnetic pulse is known as passive radar. Passive coherent location also known as PCL is a special type of passive radar, which exploits the transmitters of opportunity especially the commercial signals in the environment.

Advantages and disadvantages[ edit ] Bistatic radar principal advantages of bistatic and multistatic radar include: Lower procurement and maintenance costs if using a third-party transmitter. The RCS of both targets are specified as a vector of two elements in bistatic radar Mean radar cross section parameter of the underlying Target block.

Receiver Radar Receiver - Receives the target echo, adds receiver noise, and simulates the receiver motion. The distance between the receiver and the two targets are approximately 5 km and 15 km, respectively.

Range-Doppler Processing - Computes the range-Doppler map of bistatic radar received signal. The received signal is buffered to form a pulse burst which is then passed to a range-Doppler processor.

The processor performs a matched filter operation along the range bistatic radar and an FFT along the Doppler dimension.

Simulating a Bistatic Radar with Two Targets - MATLAB & Simulink

Exploring the Model Several dialog parameters of the model are calculated by the helper function helperslexBistaticParam. To open the function from the model, click on Modify Simulation Parameters block.

This function is executed once when the model is loaded. It exports to the workspace a structure bistatic radar fields bistatic radar referenced by the dialogs.

A bistatic radar is especially useful in case where the energy reflected by the target is very low,e. A bistatic radar is also useful for military to detect targets which use stealth technology, whereby the geometry of the target reflects bistatic radar little or no energy in the bistatic radar of the monostatic radar.
