According to APA style, the revised content would be:

Radars rely on back-scattering to generate a detectable echo from a target. A mono-static radar emits radio energy through a narrow beam, which is focused by the antenna and propagates outward through the atmosphere. Any objects in the path of the beam reflect, scatter, and absorb the energy. The target signal, which is a small portion of the reflected and scattered energy, travels back through the atmosphere and is intercepted by the receiving antenna. These signals are commonly known as echoes. The time delay between the transmitted signal and the target signal is utilized to determine the distance or slant range of the target from the radar. The direction of the focused beam at the moment the target signal is received, which refers to the azimuth and elevation angles of the antenna, determines the target's direction and height. Additional information provided by a radar about a target may include its radial velocity, as measured by a Doppler radar, or its polarizing characteristics, as measured by a dual-polarimetric radar.
