What is a monostatic radar?
A monostatic radar refers to a radar system where the transmitter and receiver are co-located at the same physical location. In a monostatic radar configuration, a single antenna is used to both transmit radar signals to a target and receive reflected echoes from the target. This configuration simplifies the design and operation of the radar system, because the same antenna performs both functions of transmitting and receiving radar waves. Monostatic radars are commonly used in various applications such as air traffic control, weather monitoring, surveillance and military operations where simple detection and tracking of targets from a fixed location is required.
What is a monostatic radar system?
A monostatic radar system encompasses all components and subsystems required to transmit radar signals to targets, receive reflected echoes from targets, and process these signals to extract information such as target range, velocity, and cross section radar (RCS). The system typically includes a transmitter that generates radar pulses or continuous wave signals, an antenna that transmits these signals to targets, and a receiver that detects echoes reflected from the targets. Signal processing algorithms are used to analyze received signals and extract relevant information about detected targets. Monostatic radar systems are versatile and widely used in civil and military applications for surveillance, navigation, weather monitoring and defense.
Monostatic detection refers to the use of monostatic radar principles in detection applications where radar signals are transmitted to a target and reflected echoes from the target are detected using the same antenna located at a fixed position. Monostatic detection involves emitting radar signals and receiving corresponding reflections to measure characteristics such as distance, speed, direction and radar cross section (RCS) of the target. This sensing technique is an integral part of various radar applications including air traffic control, ground monitoring, weather monitoring and remote sensing where accurate measurements and target detection from a single location are essential.
Radar systems can generally be classified into three types based on their operational principles and configurations:
What is monostatic sensing?
Pulse Radar: Pulse radar systems transmit short pulses of radio frequency (RF) energy, then listen for echoes reflected from objects in the environment. The delay between transmission and reception of each pulse is used to calculate the distance to the target (range). Pulse radar systems are versatile and widely used in applications such as air traffic control, weather monitoring, surveillance and military radar.
Continuous wave (CW) radar systems: CW transmits a continuous wave signal without interruption and simultaneously listens to the reflected signal to measure Doppler shift caused by moving objects. CW radar is used primarily for applications requiring accurate target speed measurement, such as speed detection, traffic monitoring, radar altimetry, and some types of weather radar.
Frequency modulated continuous wave (FMCW) radar: FMCW radar continuously varies the frequency of the transmitted signal over time in a linear or non-linear manner. It measures the range to a target by comparing the frequency of the transmitted signal with the frequency of the received signal, which has been shifted due to travel time to and from the target and back. FMCW radar offers advantages in resolution and range sensitivity, making it suitable for applications such as automotive radar, radar altimeters and ground penetrating radar.
