Abstract
An aerial detection system includes an aerial vehicle unit and a hanging platform mechanically connected to an aerial vehicle by at least one flexible link. An EM sensor and hanging platform circuitry are mounted on the hanging platform. The hanging platform circuitry processes the EM sensor output signals. The aerial vehicle unit is attached the aerial vehicle and includes AVU circuitry which processes signals output by the hanging platform circuitry. The hanging platform circuitry and AVU circuitry are connected by one or more wired and/or wireless signal connections.
Claims24
A system comprising:
- at least one flexible link;
- a hanging platform adapted to be mechanically connected to an aerial vehicle by said at least one flexible link and having mounted thereon:
- an electromagnetic (EM) sensor configured to output at least one analog signal indicative of electromagnetic field (EMF) radiation captured by said EM sensor;
- and
- a first circuitry configured to perform at least analog signal processing on an output of said EM sensor and to output at least one analog processed EM sensor signal, said first circuitry comprising a global navigation satellite system (GNSS) antenna configured to receive GNSS signals;
- and
- an aerial vehicle unit adapted to be attached to said aerial vehicle, comprising a second circuitry configured to input said at least one analog processed EM sensor signal, to perform analog to digital conversion of said input signal and digital signal processing of a result of said analog to digital conversion, and to output a result of said digital signal processing, said second circuitry comprising a GNSS receiver connected by a wired connection to an output of said GNSS antenna and configured to calculate EM sensor locations during data collection by said EM sensor.
