The general target characterization for coherent laser radars is shown to be a two-frequency bistatic scattering-amplitude matrix. This matrix is used to develop target-signature expressions for pulsed imager and 3-D imager systems.

RADAR PARAMETER GENERATION TO IDENTIFY THE TARGET Prof. Dr. W. A. Mahmoud, Dr. A. K. Sharief and Dr. F. D. Umara University of Baghdad Baghdad, IRAQ ABSTRACT Due to the popularity of radar, receivers often “hear” a great number of other transmitters in addition to their own return merely in noise.   Radar has been used for decades to study movement of insects, birds and bats. In spite of this, there are few readily available software tools for the acquisition, storage and processing of such data. Program radR was developed to solve this problem. Program radR is an open source software tool for the acquisition, storage and analysis of data from marine radars Cited by:

Radar Target Detection: Handbook of Theory and PracticeAuthor: Daniel P. Meyer. Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving.

Anatomy of a Weather Radar •Transmitter - generates the microwave signal of the correct phase and amplitude.

For a weather radar, the wavelength of the signal is ~ 10cm • Antenna - the main purpose of the antenna (also called the “dish”) is to focus the transmitted power into a small beam and also to listen and collect the returned signal.

Sometimes the WSRD Doppler Radar sees non-precipitation targets. If there is a "target" out there and it reflects radar energy back to the radar, the radar will display it as if it was precipitation.

The radar does have some logic built in to help it discriminate between precipitation and non-precipitation targets. For a radar that operates at or near the lower water vapor absorption resonance frequency of GHz, the propagation media becomes non-linear so that the 1/4 decrease in intercept signal.
