Narrative: We were departing ZZZ to ZZZ1 after dropping our passengers off at their personal hangar. As we began taxiing out; we made a call on the CTAF that we were taxiing out and planning to takeoff on RWY XX. We heard an Air Force C130 on CTAF doing work in the pattern. We made a second call as we rounded the hangars on the NE side of the airport. At that time we heard a very faint radio call of a tail number (we could not make out the N#) saying that they 'were entering the pattern; ZZZ' That is all that we heard. I made a radio call asking for the aircraft to repeat the call; and heard nothing. As we were taxiing to the hold short line; I as the PNF (pilot not flying) called for our release from Center Radio. the PF (pilot flying) was monitoring CTAF the entire time; and heard no additional radio calls from the unidentified airplane in the pattern. We stopped at the hold short line and made another radio call that we were holding short and were going to be departing RWY XX. The C130 radio'd that he would extend his orbit so that we could take off. We heard no other radio calls during that time. We crossed the hold short line and I looked and verified the final approach area for RWY XX was clear; the PF looked and verified that RWY XY Final was clear. As we were taxiing into position we heard a very faint 'you guys hold up a minute' call over CTAF. We did not know who it was for and I called over the frequency 'say again' We heard nothing. We started our takeoff run. About 5 seconds later we saw a Cessna landing on RWY XY and aborted our takeoff at a speed of about 100 knots IAS. We called out on the radio that we had made radio calls saying that we were taking off. I do not recall the exact words but we were getting chewed out for taking off while a local was trying to land. We taxed clear of the runway; reset everything; checked our brake temperatures; made another radio call and proceeded to take off uneventfully.We try to be hyper vigilant operating a high performance jet out of uncontrolled fields. It is possible; but I believe unlikely that we missed radio calls from the aircraft in question; but it is possible that we did. I believe the problem arose from a weak transmitter on the Cessna; and non standard phraseology and lack of position report calls on the CTAF. I believe that we followed the AIM guidance for operating on an uncontrolled field; by making several radio calls stating our intentions; and listening for other traffic. We heard no other position reports from the Cessna such as 'entering downwind or turning base' etc. I am not saying the other pilot did not make the calls; I'm saying we did not hear them if he did. There is also a dip in the runway that prevents you from seeing the end of RWY XY from the end of RWY XX. In addition the pilot of the Cessna did not have his landing light on; which would have helped to identify him sooner. We asked for a repeat of his initial radio call; but heard nothing. We also heard no other radio reports from any aircraft other than the C130. In addition; this could have been avoided if a proper radio call such as 'ZZZ Traffic Aircraft Y short final; landing RWY XY ZZZ' had been made instead of 'You guys hold up a minute'. We can always be more vigilant in our actions. Taxiing out while getting a clearance and setting up the FMS is a very busy time; monitoring 2 radios can be distracting. Careful attention to detail and vigilant use of the checklist and PF/PNF duties all need to be done to ensure that nothing is missed; inside and outside the airplane while operating on an uncontrolled field.
