“…From that we can estimate worst case position error. ASR-9 using Mode S has similar azimuth performance as an ASR-11 [11]. Specifications tend to be conservative and actual radar accuracy is likely better.…”

“…A comparable study was also done on the ASR-11 radar by Weber and Schanne [5]. Azimuth errors on the ARSR-4 [6], ASR-9 and ASR-11 [7] were evaluated as well. Additional studies identified vulnerabilities in secondary radar [8,9].…”

“…Despite this fact, radar, just like any other complex engineering design is prone to design flaws and problems. Previous studies [1][2][3][4][5][6][7][8][9][10] have been performed addressing and identifying the problems with radar. Some work has been done on the reliability/performance of radar, while others have been on future applications to address the current problems.…”

Detect and Avoid (DAA) systems are complex communication and locational technologies comprising multiple independent components. DAA technologies support communications between ground-based and space-based operations with aircraft. Both manned and unmanned aircraft systems (UAS) rely on DAA communication and location technologies for safe flight operations. We examined the occurrence and duration of communication losses between radar and automatic dependent surveillance-broadcast (ADS-B) systems with aircraft operating in proximate airspace using data collected during actual flight operations. Our objectives were to identify the number and duration of communication losses for both radar and ADS-B systems that occurred within a discrete time period. We also investigated whether other unique communication behavior and anomalies were occurring, such as reported elevation deviations. We found that loss of communication with both radar and ADS-B systems does occur, with variation in the length of communication losses. We also discovered that other unexpected behaviors were occurring with communications. Although our data were gathered from manned aircraft, there are also implications for UAS that are operating within active airspaces. We are unaware of any previously published work on occurrence and duration of communication losses between radar and ADS-B systems.
