RADAR is an acronym for *Radio Detecting And Ranging*. Short- wavelength microwaves are used in radar to locate objects and monitor speed.

(a) Explain what is meant by *bistatic*, *monostatic* and *quasi-monostatic* radar.

(b) The basic quantity measured by most radars, is *target range*. Write the formula for calculating the target range for: bistatic and monostatic radar.

**The strings**:
S_{7}P_{4}A_{44} (motion - oscilatory)
**The math**:

Pj Problem of Interest is of type *motion* (oscilatory - wave motion). Transmitter sends radio waves pulse in motion to object. Radio waves are reflected and pulse sent in motion to receiver.

**Bistatic**: location of transmitting antena is different from location of receiving antenna from the perspective of the target object (figure 22.3). For example, ground transmitter and airborne receiver.
**Monostatic**: transmitting antenna and receiving antenna are colocated from the perspective of the target object. For example, the use of the same antenna to transmit and receive.
**Quasi-Monostatic**: location of transmitting antenna is very close to location of receiving antenna (i.e, they are slighly separated) from the perspective of the target object.

(b)i Bistatic Range Equation: **R _{t} + R_{r} = cT_{R}**.

Where R

R

T

c is velocity of light (3 x 10

(b)ii Monostatic Range Equation:

Where R is range between transmitter and target object;

In this case, R

T

c is velocity of light (3 x 10

The *point* **.** is a mathematical abstraction. It has negligible size and a great sense of position. Consequently, it is front and center in abstract existential reasoning.

The Universe is composed of *matter* and *radiant energy*. *Matter* is any kind of *mass-energy* that moves with velocities less than the velocity of light. *Radiant energy* is any kind of *mass-energy* that moves with the velocity of light.
